Subject: [PATCH] drm/drm_vm: Mark expected switch fall-throughs
Date: Fri, 15 Feb 2019 11:05:46 -0600 [thread overview]
Message-ID: <20190215170546.GA30950@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
