2022-10-18media: videobuf2: Stop using internal dma-buf lockDmitry Osipenko
All drivers that use dma-bufs have been moved to the updated locking specification and now dma-buf reservation is guaranteed to be locked by importers during the mapping operations. There is no need to take the internal dma-buf lock anymore. Remove locking from the videobuf2 memory allocators.

2022-10-11treewide: use get_random_u32() when possibleJason A. Donenfeld
The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-10-11treewide: use get_random_{u8,u16}() when possible, part 1Jason A. Donenfeld

2022-09-30media: imx-jpeg: Lock on ioctl encoder/decoder stop cmdMing Qian
the ioctl encoder/decoder cmd is under queue lock, and buf_done is in the irq, it can't be locked with the mutex, they are not synchronized. when v4l2_update_last_buf_state is called to handle the encoder/decoder stop cmd, the last src buffer may be done at the same time. so it's possible that last_src_buf is set, but the output rdy_queue is empty, then driver won't mark it stopped, as v4l2_m2m_is_last_draining_src_buf() will always return false and v4l2_m2m_dst_buf_is_last() return false too. In this case, the drain will be blocked. add the hw lock around the ioctl encoder/decoder cmd, to synchronize with the buf_done.

But it requires buffer alignment, so driver can report the aligned resolution through the g_fmt, and report the actual resolution through the g_selection. For encoder, it even support to encode a smaller jpeg than the original picture through s_selection api. For the decoder, we do not support cropping a portion smaller than the original picture, due to hardware limitations (wrapper side).

2022-09-27media: mediatek: vcodec: Drop platform_get_resource(IORESOURCE_IRQ)Nícolas F. R. A. Prado
Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") removed support for calling platform_get_resource(..., IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of mtk-vcodec's encoder was still making use of it. This caused the encoder driver to fail probe. Since the platform_get_resource() call was only being used to check for the presence of the interrupt (its returned resource wasn't even used) and platform_get_irq() was already being used to get the IRQ, simply drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the failure of platform_get_irq(), to get the driver probing again.

2022-09-27media: v4l2-ioctl.c: fix incorrect error pathHans Verkuil
If allocating array_buf fails, or copying data from userspace into that buffer fails, then just free memory and return the error. Don't attempt to call video_put_user() since there is no point, and it would copy back data on error even if INFO_FL_ALWAYS_COPY wasn't set. So if writing the array back to userspace fails, then don't go to out_array_args, instead just continue with the regular code that just returns the error unless 'always_copy' is set. Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag since they now need it. Before this worked due to this buggy code, but now that that is fixed these ioctls need to set this flag explicitly.
