Subject[PATCH 5.1 057/138] gpu: ipu-v3: image-convert: Fix input bytesperline width/height align
Date
[ Upstream commit ff391ecd65a1b8324c49046c3db98d9c8ab29af9 ]

The output width and height alignment values were being used in the
input bytesperline calculation. Fix by separating local vars w_align
and h_align into w_align_in, h_align_in, w_align_out, and h_align_out.

Fixes: d966e23d61a2c ("gpu: ipu-v3: image-convert: fix bytesperline
adjustment")
