Subject: [PATCH] drm/framebuffer: Pitch checks aren't valid for non-linear
|
|
modifiers
|
|
|
|
Pitch has no meaning if the modifier isn't DRM_FORMAT_MOD_LINEAR
|
|
as there is no guarantee that the value passed follows the
|
|
pattern that pitch * height = size.
|
|
|
|
Remove that check from framebuffer_check.
