Subject: [PATCH] net: sched: cls_api: fix dead code in switch
Date: Wed, 25 Jul 2018 09:07:24 -0500	[thread overview]
Message-ID: <20180725140724.GA23053@embeddedor.com> (raw)

Code at line 1850 is unreachable. Fix this by removing the break
statement above it, so the code for case RTM_GETCHAIN can be
properly executed.

Addresses-Coverity-ID: 1472050 ("Structurally dead code")
Fixes: 32a4f5ecd738 ("net: sched: introduce chain object to uapi")
