2016-11-25mvpp2: use correct size for memsetArnd Bergmann1-1/+1
gcc-7 detects a short memset in mvpp2, introduced in the original merge of the driver: drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_cls_init': drivers/net/ethernet/marvell/mvpp2.c:3296:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size] The result seems to be that we write uninitialized data into the flow table registers, although we did not get any warning about that uninitialized data usage.

I managed to reproduce similar errors on another Haswell based machine where touchscreen initialization fails maybe in every 1/5 - 1/2 boots.

2016-11-25mfd: wm8994-core: Don't use managed regulator bulk get APIViresh Kumar1-3/+11
The kernel WARNs and then crashes today if wm8994_device_init() fails after calling devm_regulator_bulk_get(). That happens because there are multiple devices involved here and the order in which managed resources are freed isn't correct. The regulators are added as children of wm8994->dev. Whereas, devm_regulator_bulk_get() receives wm8994->dev as the device, though it gets the same regulators which were added as children of wm8994->dev earlier. During failures, the children are removed first and the core eventually calls regulator_unregister() for them. As regulator_put() was never done for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at WARN_ON(rdev->open_count); And eventually it crashes from debugfs_remove_recursive(). --------x------------------x---------------- wm8994 3-001a: Device is not a WM8994, ID is 0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at /mnt/ssd/all/work/repos/devel/linux/drivers/regulator/core.c:4072 regulator_unregister+0xc8/0xd0 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.8.0-rc6-00154-g54fe84cbd50b #41 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c010e24c>] (unwind_backtrace) from [<c010af38>] (show_stack+0x10/0x14) [<c010af38>] (show_stack) from [<c032a1c4>] (dump_stack+0x88/0x9c) [<c032a1c4>] (dump_stack) from [<c011a98c>] (__warn+0xe8/0x100) [<c011a98c>] (__warn) from [<c011aa54>] (warn_slowpath_null+0x20/0x28) [<c011aa54>] (warn_slowpath_null) from [<c0384a0c>] (regulator_unregister+0xc8/0xd0) [<c0384a0c>] (regulator_unregister) from [<c0406434>] (release_nodes+0x16c/0x1dc) [<c0406434>] (release_nodes) from [<c04039c4>] (__device_release_driver+0x8c/0x110) [<c04039c4>] (__device_release_driver) from [<c0403a64>] (device_release_driver+0x1c/0x28) [<c0403a64>] (device_release_driver) from [<c0402b24>] (bus_remove_device+0xd8/0x104) [<c0402b24>] (bus_remove_device) from [<c03ffcd8>] (device_del+0x10c/0x218) [<c03ffcd8>] (device_del) from [<c0404e4c>] (platform_device_del+0x1c/0x88) [<c0404e4c>] (platform_device_del) from [<c0404ec4>] (platform_device_unregister+0xc/0x20) [<c0404ec4>] (platform_device_unregister) from [<c0428bc0>] (mfd_remove_devices_fn+0x5c/0x64) [<c0428bc0>] (mfd_remove_devices_fn) from [<c03ff9d8>] (device_for_each_child_reverse+0x4c/0x78) [<c03ff9d8>] (device_for_each_child_reverse) from [<c04288c4>] (mfd_remove_devices+0x20/0x30) [<c04288c4>] (mfd_remove_devices) from [<c042758c>] (wm8994_device_init+0x2ac/0x7f0) [<c042758c>] (wm8994_device_init) from [<c04f14a8>] (i2c_device_probe+0x178/0x1fc) [<c04f14a8>] (i2c_device_probe) from [<c04036fc>] (driver_probe_device+0x214/0x2c0) [<c04036fc>] (driver_probe_device) from [<c0403854>] (__driver_attach+0xac/0xb0) [<c0403854>] (__driver_attach) from [<c0401a74>] (bus_for_each_dev+0x68/0x9c) [<c0401a74>] (bus_for_each_dev) from [<c0402cf0>] (bus_add_driver+0x1a0/0x218) [<c0402cf0>] (bus_add_driver) from [<c040406c>] (driver_register+0x78/0xf8) [<c040406c>] (driver_register) from [<c04f20a0>] (i2c_register_driver+0x34/0x84) [<c04f20a0>] (i2c_register_driver) from [<c01017d0>] (do_one_initcall+0x40/0x170) [<c01017d0>] (do_one_initcall) from [<c0a00dbc>] (kernel_init_freeable+0x15c/0x1fc) [<c0a00dbc>] (kernel_init_freeable) from [<c06e07b0>] (kernel_init+0x8/0x114) [<c06e07b0>] (kernel_init) from [<c0107978>] (ret_from_fork+0x14/0x3c) ---[ end trace 0919d3d0bc998260 ]--- [snip..] Unable to handle kernel NULL pointer dereference at virtual address 00000078 pgd = c0004000 [00000078] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W 4.8.0-rc6-00154-g54fe84cbd50b #41 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) task: ee874000 task.stack: ee878000 PC is at down_write+0x14/0x54 LR is at debugfs_remove_recursive+0x30/0x150 [snip..] [<c06e489c>] (down_write) from [<c02e9954>] (debugfs_remove_recursive+0x30/0x150) [<c02e9954>] (debugfs_remove_recursive) from [<c0382b78>] (_regulator_put+0x24/0xac) [<c0382b78>] (_regulator_put) from [<c0382c1c>] (regulator_put+0x1c/0x2c) [<c0382c1c>] (regulator_put) from [<c0406434>] (release_nodes+0x16c/0x1dc) [<c0406434>] (release_nodes) from [<c04035d4>] (driver_probe_device+0xec/0x2c0) [<c04035d4>] (driver_probe_device) from [<c0403854>] (__driver_attach+0xac/0xb0) [<c0403854>] (__driver_attach) from [<c0401a74>] (bus_for_each_dev+0x68/0x9c) [<c0401a74>] (bus_for_each_dev) from [<c0402cf0>] (bus_add_driver+0x1a0/0x218) [<c0402cf0>] (bus_add_driver) from [<c040406c>] (driver_register+0x78/0xf8) [<c040406c>] (driver_register) from [<c04f20a0>] (i2c_register_driver+0x34/0x84) [<c04f20a0>] (i2c_register_driver) from [<c01017d0>] (do_one_initcall+0x40/0x170) [<c01017d0>] (do_one_initcall) from [<c0a00dbc>] (kernel_init_freeable+0x15c/0x1fc) [<c0a00dbc>] (kernel_init_freeable) from [<c06e07b0>] (kernel_init+0x8/0x114) [<c06e07b0>] (kernel_init) from [<c0107978>] (ret_from_fork+0x14/0x3c) Code: e1a04000 f590f000 e3a03001 e34f3fff (e1902f9f) ---[ end trace 0919d3d0bc998262 ]--- --------x------------------x---------------- Fix the kernel warnings and crashes by using regulator_bulk_get() instead of devm_regulator_bulk_get() and explicitly freeing the supplies in exit paths.

2016-11-24i2c: designware: fix rx fifo depth trackingRussell King1-1/+1
When loading the TX fifo to receive bytes on the I2C bus, we incorrectly count the number of bytes: rx_limit = dev->rx_fifo_depth - dw_readl(dev, DW_IC_RXFLR); while (buf_len > 0 && tx_limit > 0 && rx_limit > 0) { if (rx_limit - dev->rx_outstanding <= 0) break; rx_limit--; dev->rx_outstanding++; } DW_IC_RXFLR indicates how many bytes are available to be read in the FIFO, dev->rx_fifo_depth is the FIFO size, and dev->rx_outstanding is the number of bytes that we've requested to be read so far, but which have not been read. Firstly, increasing dev->rx_outstanding and decreasing rx_limit and then comparing them results in each byte consuming "two" bytes in this tracking, so this is obviously wrong. Secondly, the number of bytes that _could_ be received into the FIFO at any time is the number of bytes we have so far requested but not yet read from the FIFO - in other words dev->rx_outstanding. So, in order to request enough bytes to fill the RX FIFO, we need to request dev->rx_fifo_depth - dev->rx_outstanding bytes. Modifying the code thusly results in us reaching the maximum number of bytes outstanding each time we queue more "receive" operations, provided the transfer allows that to happen.

Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e. Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP mode, those signals will cause h-time larger than normal and reduce FPS.

2016-11-23xc2028: Fix use-after-free bug properlyTakashi Iwai1-21/+16
The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried to address the reported use-after-free by clearing the reference. However, it's clearing the wrong pointer; it sets NULL to priv->ctrl.fname, but it's anyway overwritten by the next line memcpy(&priv->ctrl, p, sizeof(priv->ctrl)). OTOH, the actual code accessing the freed string is the strcmp() call with priv->fname: if (!firmware_name[0] && p->fname && priv->fname && strcmp(p->fname, priv->fname)) free_firmware(priv); where priv->fname points to the previous file name, and this was already freed by kfree(). For fixing the bug properly, this patch does the following: - Keep the copy of firmware file name in only priv->fname, priv->ctrl.fname isn't changed; - The allocation is done only when the firmware gets loaded; - The kfree() is called in free_firmware() commonly Fixes: commit 8dfbcc4351a0 ('[media] xc2028: avoid use after free') Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue. v2: agd: fix typo Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98505 Signed-off-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: <stable@vger.kernel.org> # 4.8+ Reviewed-by: Alex Deucher <alexander.deucher@amd.com>

2016-11-23HID: hid-sensor-hub: clear memory to avoid random dataSong Hongyan1-0/+1
When user tried to read some fields like hysteresis from IIO sysfs on some systems, it fails. The reason is that this field is a byte field and caller of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function sensor_hub_get_feature() copies the single byte from the report to the caller buffer and returns "1" as the number of bytes copied. So caller can use the return value. But this is done by multiple callers, so if we just change the sensor_hub_get_feature so that caller buffer is initialized with 0s then we don't to change all functions.
