From ff391ecd65a1b8324c49046c3db98d9c8ab29af9 Mon Sep 17 00:00:00 2001 From: Steve Longerbeam Date: Tue, 11 Jun 2019 18:16:55 -0700 Subject: gpu: ipu-v3: image-convert: Fix input bytesperline width/height align 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.
