2021-08-25net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warningsMichael Riesch1-9/+0
This reverts commit 2c896fb02e7f65299646f295a007bda043e0f382 "net: stmmac: dwmac-rk: add pd_gmac support for rk3399" and fixes unbalanced pm_runtime_enable warnings. In the commit to be reverted, support for power management was introduced to the Rockchip glue code. Later, power management support was introduced to the stmmac core code, resulting in multiple invocations of pm_runtime_{enable,disable,get_sync,put_sync}. The multiple invocations happen in rk_gmac_powerup and stmmac_{dvr_probe, resume} as well as in rk_gmac_powerdown and stmmac_{dvr_remove, suspend}, respectively, which are always called in conjunction.

2021-08-25Revert "USB: serial: ch341: fix character loss at high transfer rates"Johan Hovold1-1/+0
This reverts commit 3c18e9baee0ef97510dcda78c82285f52626764b. These devices do not appear to send a zero-length packet when the transfer size is a multiple of the bulk-endpoint max-packet size. This means that incoming data may not be processed by the driver until a short packet is received or the receive buffer is full. Revert back to using endpoint-sized receive buffers to avoid stalled reads.

2021-08-24drm/amdgpu: Fix build with missing pm_suspend_target_state module exportBorislav Petkov1-1/+1
Building a randconfig here triggered: ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! because the module export of that symbol happens in kernel/power/suspend.c which is enabled with CONFIG_SUSPEND. The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for CONFIG_PM_SLEEP which is defined like this: config PM_SLEEP def_bool y depends on SUSPEND || HIBERNATE_CALLBACKS and that randconfig has: # CONFIG_SUSPEND is not set CONFIG_HIBERNATE_CALLBACKS=y leading to the module export missing. Change the ifdeffery to depend directly on CONFIG_SUSPEND.

2021-08-24net: dsa: mv88e6xxx: Update mv88e6393x serdes errataNathan Rossi1-5/+6
In early erratas this issue only covered port 0 when changing from [x]MII (rev A 3.6). In subsequent errata versions this errata changed to cover the additional "Hardware reset in CPU managed mode" condition, and removed the note specifying that it only applied to port 0. In designs where the device is configured with CPU managed mode (CPU_MGD), on reset all SERDES ports (p0, p9, p10) have a stuck power down bit and require this initial power up procedure. As such apply this errata to all three SERDES ports of the mv88e6393x. Signed-off-by: Nathan Rossi <nathan.rossi@digi.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-08-23Revert "media: dvb header files: move some headers to staging"Linus Torvalds4-506/+3
This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177. It turns out that some user-space applications use these uapi header files, so even though the only user of the interface is an old driver that was moved to staging, moving the header files causes unnecessary pain. Generally, we really don't want user space to use kernel headers directly (exactly because it causes pain when we re-organize), and instead copy them as needed. But these things happen, and the headers were in the uapi directory, so I guess it's not entirely unreasonable.

2021-08-23opp: core: Check for pending links before reading required_opp pointersMarijn Suijten1-4/+4
Commit 4fa82a87ba55 ("opp: Allow required-opps to be used for non genpd use cases") dereferences the pointers in required_opp_tables but these might be set to an ERR_PTR if the list still has lazy links pending, resulting in segfaults. Prior to this patch IS_ERR was also checked on required_opp_tables[i] before reading ->is_genpd inside _opp_table_alloc_required_tables, which is at the same time the predicate to add this table to the lazy list. This segfault is solved by reordering the checks to bail on lazy pending tables before reading ->is_genpd.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer2-17/+30
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0. This makes sure the delayed work doesn't run at unexpected times, and allows it to be lock-free. v2: * Use cancel_delayed_work_sync & mutex_trylock instead of mod_delayed_work. v3: * Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König) v4: * Fix race condition between amdgpu_gfx_off_ctrl incrementing adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off checking for it to be 0 (Evan Quan) Cc: stable@vger.kernel.org Reviewed-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> # v3 Acked-by: Christian König <christian.koenig@amd.com> # v3 Signed-off-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

The devlink dev info command reports version information about the device and firmware running on the board. This includes the "board.id" field which is supposed to represent an identifier of the board design. The ice driver uses the Product Board Assembly identifier for this. In some cases, the PBA is not present in the NVM. If this happens, devlink dev info will fail with an error. Instead, modify the ice_info_pba function to just exit without filling in the context buffer. This will cause the board.id field to be skipped.
