Subject: [PATCH 2/4] 9p/rdma: remove useless check in cm_event_handler
Date: Fri,  7 Sep 2018 18:50:55 +0200	[thread overview]
Message-ID: <1536339057-21974-3-git-send-email-asmadeus@codewreck.org> (raw)
In-Reply-To: <1536339057-21974-1-git-send-email-asmadeus@codewreck.org>

From: Dominique Martinet <dominique.martinet@cea.fr>

the client c is always dereferenced to get the rdma struct, so c has to
be a valid pointer at this point.
Gcc would optimize that away but let's make coverity happy...
