While refactoring code the return statement became corrupted, fix it by

Hi,
This series adds support for V4L2_FIELD_ALTERNATE to rcar-vin. This

The variable to hold the video source information dimensions was poorly
named 'source'. This is confusing as a lot of other members of structs
share the same name with different purposes, rename it src_rect in
preparation of refactoring code.

The hardware is capable to passing V4L2_FIELD_ALTERNATE to user-space.

With support for V4L2_FIELD_ALTERNATE added it's possible to clean up

poll_wait uses &buf->done, but buf is NULL. Move the poll_wait to later
in the function once buf is correctly set and only call it if it is
non-NULL.
