Subject: [PATCH RESEND][next] drm/i915/gem: Fix fall-through warnings for
 Clang
Message-ID: <20210305095524.GA141804@embeddedor>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a return statement instead of letting the code fall
through to the next case.
