Subject: [PATCH] drm/ast: Fix invalid usage of AST_MAX_HWC_WIDTH in cursor atomic_check
Git-commit: ee4a92d690f30f3793df942939726bec0338e65b
Patch-mainline: v5.13-rc1
References: git-fixes
Use AST_MAX_HWC_HEIGHT for setting offset_y in the cursor plane's
atomic_check. The code used AST_MAX_HWC_WIDTH instead. This worked
because both constants has the same value.
