Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in
(or viceversa) causes build errors:
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete':
atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module'

or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module'
This is caused by the file atmel-isc-base.c which is common code between
the two drivers.
The solution is to create another Kconfig symbol that is automatically
selected and generates the module atmel-isc-base.ko. This module can be
loaded when both drivers are modules, or built-in when at least one of them
is built-in.

constify all places where mxc_jpeg_fmt is used, in function arguments,
return values and pointers. On top of that, make the name a pointer to

The saa6588_ioctl() function expects to get called from other kernel
functions with a 'saa6588_command' pointer, but I found nothing stops it
from getting called from user space instead, which seems rather dangerous.
The same thing happens in the davinci vpbe driver with its VENC_GET_FLD
command.
As a quick fix, add a separate .command() callback pointer for this
driver and change the two callers over to that. This change can easily
get backported to stable kernels if necessary, but since there are only
two drivers, we may want to eventually replace this with a set of more
specialized callbacks in the long run.

We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use flexible-array members in struct hfi_msg_sys_property_info_pkt and
hfi_msg_session_property_info_pkt instead of one-element arrays, and
refactor the code accordingly.
Also, this helps with the ongoing efforts to enable -Warray-bounds by
fixing the following warnings:
CC [M] drivers/media/platform/qcom/venus/hfi_msgs.o

Right now, there are two calls for xvip_get_format_by_fourcc().
If the first one fails, it is called again in order to pick
the first available format: V4L2_PIX_FMT_YUYV.
This ends by producing a smatch warnings:
drivers/media/platform/xilinx/xilinx-dma.c:555 __xvip_dma_try_format() error: 'info' dereferencing possible ERR_PTR()
drivers/media/platform/xilinx/xilinx-dma.c: drivers/media/platform/xilinx/xilinx-dma.c:664 xvip_dma_init() error: 'dma->fmtinfo' dereferencing possible ERR_PTR()
as it is hard for an static analyzer to ensure that calling
xvip_get_format_by_fourcc(XVIP_DMA_DEF_FORMAT) won't return an
error.
So, better to optimize the logic, ensuring that the function
will never return an error.
