From d966e23d61a2c3769ed0c0a3c6e20b300a313317 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 18 Sep 2018 11:34:18 +0200 Subject: gpu: ipu-v3: image-convert: fix bytesperline adjustment 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.
