Smatch reports two issues:
drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_num' 3 <= 4
drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_den' 3 <= 4
It seems that there's actually a bug here: the same var (idx) is used
as an index for vertical and horizontal scaling arrays. However,
there are 4 elements on the h arrays, and only 3 at the v ones.
On the first loop, it may select index 4 for the horizontal array.
In this case, if the second loop fails to select an index, the
code would keep using 4 for the vertical array, with is past of
the array sizes.
The intent here seems to use index 0, if the scale is not found.
So, use a separate var for the vertical index.

This seems to be due to some bad optimization done by gcc.

issue.

Commits a0f10c131c and
6c9fe76536 ("media: s5p-mfc: fix broken
pointer cast on 64bit arch") fixed issue with lossy cast on 64-bit
architectures. However it also removed __iomem attribute from that cast.
This leads to sparse warnings. This patch fixes those warnings by adding
__iomem cast in case of v6+ code version and replacing readl/writel by
simple u32 load/store operations in case of v5 code (which is called on
system memory allocated by dma_alloc_coherent() instead of io registers).

My static checker warns that the name of the port can be 15 characters
when you consider the NUL terminator and that's one more than the 14
characters in name[]. Maybe it's an off-by-one?
It's unlikely that we hit the limit and even if we do the overflow will
only affect one of the two bytes of padding so it's harmless. Still
let's fix it and also change the sprintf() to snprintf().

The RGB444 format swapped the red and blue components, fix this.
Rather than making a new BGR444 format (as I proposed initially), Jon prefers
to just fix this and return the colors in the right order. I think that makes
sense in this case.
Since the RGB444 pixel format is deprecated due to the ambiguous specification
of the alpha component we use the XRGB444 pixel format instead (specified as having
no alpha channel).

Two reasons for this: the v4l2_ctrl_handler_init() call must come
before the ov7670 is loaded (otherwise the ov7670 won't know that
its controls should be added to the bridge driver), and the
v4l2_ctrl_handler_free() call at the end should only be called if
