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. Signed-off-by: Kévin L'hôpital <redacted>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. Maxime
All right, I will add this explanation. Thank you very much for the review Kévin -- Kevin L'Hopital, Bootlin Embedded Linux and kernel engineering https://bootlin.com
