git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging/IIO driver updates from Greg KH: "Here is the large set of staging and IIO driver changes for 5.8-rc1 Nothing major, but a lot of new IIO drivers are included in here, along with other core iio cleanups and changes. On the staging driver front, again, nothing noticable. No new deletions or additions, just a ton of tiny cleanups all over the tree done by a lot of different people. Most coding style, but many actual real fixes and cleanups that are nice to see.

2020-06-03atomisp: avoid warning about unused functionLinus Torvalds1-6/+4
The atomisp_mrfld_power() function isn't actually ever called, because the two call-sites have commented out the use because it breaks on some platforms. That results in: drivers/staging/media/atomisp/pci/atomisp_v4l2.c:764:12: warning: ‘atomisp_mrfld_power’ defined but not used [-Wunused-function] 764 | static int atomisp_mrfld_power(struct atomisp_device *isp, bool enable) | ^~~~~~~~~~~~~~~~~~~ during the build. Rather than commenting out the use entirely, just disable it semantically instead (using a "0 &&" construct), leaving the call in place from a syntax standpoint, and avoiding the warning. I really don't want my builds to have any warnings that can then hide real issues. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: - Media documentation is now split into admin-guide, driver-api and userspace-api books (a longstanding request from Jon); - The media Kconfig was reorganized, in order to make easier to select drivers and their dependencies; - The testing drivers now has a separate directory; - added a new driver for Rockchip Video Decoder IP; - The atomisp staging driver was resurrected. It is meant to work with 4 generations of cameras on Atom-based laptops, tablets and cell phones. So, it seems worth investing time to cleanup this driver and making it in good shape. - Added some V4L2 core ancillary routines to help with h264 codecs; - Added an ov2740 image sensor driver; - The si2157 gained support for Analog TV, which, in turn, added support for some cx231xx and cx23885 boards to also support analog standards; - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera is located at the device; - VIDIOC_ENUM_FMT was extended to support MC-centric devices; - Lots of drivers improvements and cleanups. * tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (503 commits) media: Documentation: media: Refer to mbus format documentation from CSI-2 docs media: s5k5baf: Replace zero-length array with flexible-array media: i2c: imx219: Drop <linux/clk-provider.h> and <linux/clkdev.h> media: i2c: Add ov2740 image sensor driver media: ov8856: Implement sensor module revision identification media: ov8856: Add devicetree support media: dt-bindings: ov8856: Document YAML bindings media: dvb-usb: Add Cinergy S2 PCIe Dual Port support media: dvbdev: Fix tuner->demod media controller link media: dt-bindings: phy: phy-rockchip-dphy-rx0: move rockchip dphy rx0 bindings out of staging media: staging: dt-bindings: phy-rockchip-dphy-rx0: remove non-used reg property media: atomisp: unify the version for isp2401 a0 and b0 versions media: atomisp: update TODO with the current data media: atomisp: adjust some code at sh_css that could be broken media: atomisp: don't produce errs for ignored IRQs media: atomisp: print IRQ when debugging media: atomisp: isp_mmu: don't use kmem_cache media: atomisp: add a notice about possible leak resources media: atomisp: disable the dynamic and reserved pools media: atomisp: turn on camera before setting it ...

Just take copy_from_user() out of do_insn_ioctl() into the caller and have compat_insn() build a native version and pass it to do_insn_ioctl() directly. One difference from the previous commits is that the helper used to convert 32bit variant to native has two users - compat_insn() and compat_insnlist(). The latter will be converted in next commit; for now we simply split the helper in two variants - "userland 32bit to kernel native" and "userland 32bit to userland native". The latter is renamed old get_compat_insn(); it will be gone in the next commit. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2020-05-28staging: greybus: sdio: Respect the cmd->busy_timeout from the mmc coreUlf Hansson1-3/+7
Using a fixed 1s timeout for all commands is a bit problematic. For some commands it means waiting longer than needed for the timeout to expire, which may not a big issue, but still. For other commands, like for an erase (CMD38) that uses a R1B response, may require longer timeouts than 1s. In these cases, we may end up treating the command as it failed, while it just needed some more time to complete successfully. Fix the problem by respecting the cmd->busy_timeout, which is provided by the mmc core.

This patch removes the expression that makes use of a priori knowledge about channel numbers to calculate an array index. The expression 'peer = 1 - channel' utilizes the fact that an USB interface that operates on the asynchronous data of the Network only has two endpoints. Hence, channel being 0 or 1. The replacement is more simple and less confusing when reading the code.
