For planar formats, bytesperline does not depend on BPP. It must always be larger than width and aligned to tile width alignment restrictions. The input bytesperline to ipu_image_convert_adjust() may be uninitialized, so don't rely on input bytesperline as the minimum value for clamp_align(). Use 2 << w_align as the minimum instead.
