Mauro Carvalho Chehab 24cc418b5b media: vim2m: better handle cap/out buffers with different sizes 
The vim2m driver doesn't enforce that the capture and output
buffers would have the same size. Do the right thing if the
buffers are different, zeroing the buffer before writing,
ensuring that lines will be aligned and it won't write past
the buffer area.

This is a temporary fix.

A proper fix is to either implement a simple scaler at vim2m,
or to better define the behaviour of M2M transform drivers
at V4L2 API with regards to its capability of scaling the
image or not.

In any case, such changes would deserve a separate patch
anyway, as it would imply on some behavoral change.

Also, as we have an actual bug of writing data at wrong
places, let's fix this here, and add a mental note that
we need to properly address it.
