This paragraph was added by commit a42b57f5 ("V4L/DVB: Documentation: add v4l2-controls.txt documenting the new controls API") back in 2010, when the controls API has been improved. Nowadays it is a bit anachronistic, so remove it. The same information is stated in up-to-date wording a few paragraphs later > You’re done! And this is sufficient for most of the drivers we have. No > need to do any validation of control values, or implement QUERYCTRL, > QUERY_EXT_CTRL and QUERYMENU. And G/S_CTRL as well as G/TRY/S_EXT_CTRLS > are automatically supported. Signed-off-by:

The code snippet showing how to add controls to the driver’s top-level struct is present twice, but only the second time it is split in the V4L2 and subdev cases. Consolidate everything at the beginning. Also remove the "Where foo->bar is of type struct baz" sentences, this obvious from the code. Signed-off-by:

Since the beginning the second clock ('special', 'sclk') was optional and it is not available on some variants of Exynos SoCs (i.e. Exynos5420 with v7 of MFC hardware). However commit 1bce6fb3 ("[media] s5p-mfc: Rework clock handling") made handling of all specified clocks mandatory. This patch restores original behavior of the driver and fixes its operation on Exynos5420 SoCs.

Fix v4l2_fourcc define to use "U" cast to avoid shifting signed 32-bit value by 31 bits problem. This isn't a problem for kernel builds with gcc. This could be problem since this header is part of public API which could be included for builds using compilers that don't handle this condition safely resulting in undefined behavior.

The helpers rvin_power_{on,off} deal with both VIN and the parallel subdevice power. This makes it hard to merge the Gen2 and Gen3 open/release functions. Move the VIN power handling directly to the open/release functions to prepare for the merge. Signed-off-by: -

This splits the Atmel ISC driver into a common base: atmel-isc-base.c and the driver probe/dt part , atmel-sama5d2-isc.c This is needed to keep a common ground for the sensor controller which will be reused. The atmel-isc will use the common symbols inside the atmel-isc-base Future driver will also use the same symbols and redefine different aspects, for a different version of the ISC. This is done to avoid complete code duplication by creating a totally different driver for the new variant of the ISC. Signed-off-by:

When the application calls VIDIOC_DQBUF with the DMABUF memory type, the v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf file descriptors. However, the current documentation does not explain whether those are new file descriptors referring to the same DMA-bufs or just the same integers as passed to VIDIOC_QBUF back in time. Clarify the documentation that it's the latter. Signed-off-by:

There two callers of stv090x_setup_compound manage the allocation and freeing if state there is an error condition from stv090x_setup_compound. Currently function stv090x_setup_compound also frees the state object too, leading to a double free in the callers of this function. Fix this by removing the extraneous free in stv090x_setup_compound and just leave the callers handle the allocation/free'ing. Signed-off-by:

Pull x86 fixes from Thomas Gleixner: "The accumulated fixes from this and last week: - Fix vmalloc TLB flush and map range calculations which lead to stale TLBs, spurious faults and other hard to diagnose issues. - Use fault_in_pages_writable() for prefaulting the user stack in the FPU code as it's less fragile than the current solution - Use the PF_KTHREAD flag when checking for a kernel thread instead of current->mm as the latter can give the wrong answer due to use_mm() - Compute the vmemmap size correctly for KASLR and 5-Level paging. Otherwise this can end up with a way too small vmemmap area. - Make KASAN and 5-level paging work again by making sure that all invalid bits are masked out when computing the P4D offset. This worked before but got broken recently when the LDT remap area was moved. - Prevent a NULL pointer dereference in the resource control code which can be triggered with certain mount options when the requested resource is not available. - Enforce ordering of microcode loading vs. perf initialization on secondary CPUs. Otherwise perf tries to access a non-existing MSR as the boot CPU marked it as available. - Don't stop the resource control group walk early otherwise the control bitmaps are not updated correctly and become inconsistent. - Unbreak kgdb by returning 0 on success from kgdb_arch_set_breakpoint() instead of an error code. - Add more Icelake CPU model defines so depending changes can be queued in other trees" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/microcode, cpuhotplug: Add a microcode loader CPU hotplug callback x86/kasan: Fix boot with 5-level paging and KASAN x86/fpu: Don't use current->mm to check for a kthread x86/kgdb: Return 0 from kgdb_arch_set_breakpoint() x86/resctrl: Prevent NULL pointer dereference when local MBM is disabled x86/resctrl: Don't stop walking closids when a locksetup group is found x86/fpu: Update kernel's FPU state before using for the fsave header x86/mm/KASLR: Compute the size of the vmemmap section properly x86/fpu: Use fault_in_pages_writeable() for pre-faulting x86/CPU: Add more Icelake model numbers mm/vmalloc: Avoid rare case of flushing TLB with weird arguments mm/vmalloc: Fix calculation of direct map addr range -
