Subject: drm/modes: drop maxPitch from drm_mode_validate_size
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3e70292cd4a002cd799a1cd4115286cba3933d6d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/modes: drop maxPitch from drm_mode_validate_size

Totally unused and actually redundant with maxX for display mode
validation. The fb helper otoh needs to check pitch limits,
but that is delegated into drivers instead.
