[libcamera-devel] [PATCH] libcamera: pipeline: ipu3: change IF_CROP_MAX to 40

[Dave Olsthoorn]

The value of IF_CROP_MAX seems to be a typo. A resolution of 40x540 seems
unlikely and excludes camera's with a 640x480 resolution, like the OV7251
in several Microsoft Surface products, from working.

This patch corrects the value to 40 since a minimal resolution of 40x40
seems more logical.
