Subject: [PATCH] drm/nouveau: mark expected switch fall-through
Date: Tue, 29 Jan 2019 14:30:46 -0600	[thread overview]
Message-ID: <20190129203046.GA28384@embeddedor> (raw)

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warning:

drivers/gpu/drm/nouveau/nouveau_bo.c:1434:53: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.
