gpu: ipu-v3: image-convert: Fix input bytesperline for packed formats
[ 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")
