[PATCH] v4l2: do not force buffer size to be multiple of PAGE_SIZE

From: Tuukka Toivonen When the image size (bytesperline*height) is not multiple of PAGE_SIZE, v4l2 rounded the required buffer size to be multiple of PAGE_SIZE. This prevented user space to store images directly into userptr buffers which were not multiple of PAGE_SIZE. This constraint is removed

Do not restrict image buffer allocation to multiple of PAGE_SIZE

This patchset removes the constraint which enforced image buffer size to be multiple of PAGE_SIZE. It improves efficiency by allowing storing images directly to Ximage buffers removing the need to copy image data. It is tested with mmap and userptr methods, changes to V4L1 compatibility layer are
