[ Upstream commit bca4d70cf1b8f6478a711c448a3a1e47b794b162 ]
The input bytesperline calculation for packed pixel formats was incorrect. The min/max clamping values must be multiplied by the packed bits-per-pixel. This was causing corrupted converted images when the input format was RGB4 (probably also other input packed formats).
Fixes: d966e23d61a2c ("gpu: ipu-v3: image-convert: fix bytesperline adjustment")
