Hi Manju,
Thanks for the RFC. I've reviewed it, and there are a few systematic issues
but nothing major. I'm not sure if the same also apply to other patches.
Notning really related to V4L2 yet.
- If function returns no meaningful value it should be void.
- Returning early may easily allow unindenting the res of the function.
- No need for extra parenthesis in assignments.
- Using a temporary variable do not always improve readability in register
writes.

No need for parentheses in such cases and I don't think they improve
readability. Similar cases can be found throughout the patch.

The three above lines can be move out of the conditions, index to the array
is rsz_id.

And the three above lines may be removed.

Numerical index could be replaced by e.g. definition RSZ_A_IDX.

If the function can't fail it should have void return type.

Not really a comment to the patxh, but what are the meanings of bad and sad
