Subject: [PATCH] checkpatch: Include GEM_BUG_xxx variant in the excluded check list
Date:   Wed, 14 Jun 2023 12:49:55 -0400

GEM_BUG_ON is usually compiled as WARN.  You have to change to
debug configuration to get this to be BUG.

checkpatch flags this a WARN level issue.

Since this is a i915 local debug macro, allow its use in checkpatch.pl.

Fixes: 69d517e6e210 ("checkpatch: warn on usage of VM_BUG_ON() and other BUG variants")
