Maybe we should use the kernel's ALIGN macro here? ALIGN(pitch, pitch_align). I don't know, it might just make it unclear.
We don't want to align the pitch, we want to check if it is aligned.
Ah, I meant IS_ALIGNED, in linux/kernel.h:
#define IS_ALIGNED(x, a) (((x) & ((typeof(x))(a) - 1)) == 0)
Should definitely be using it here, instead.
Care to send a patch?
