10-bit bayer formats are aligned to 16 bits in memory, so this is
what needs to be used as bpp for calculating the size of the
buffers to allocate.

Generally speaking, you should also explain why it's not an issue for
the callers. Depending on what that function is supposed to be doing
(returning the padded bits or the padded bits per pixel), your patch
could be either right or wrong.

Since all the callers are using it to generate the number of bytes per
line, your patch is indeed correct. But it should be mentionned in the
commit log.

All right, I will add this explanation.

Thank you very much for the review

Kévin
