Subject: [PATCH] staging: vc04_services: Delete unnecessary NULL check
Message-ID: <526ec2ff-6277-4d5d-b2d9-63b087a97c7c@moroto.mountain>
Precedence: bulk
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline

The "state" pointer points to an offset in the middle of the "mgmt"
struct so it can't possibly be NULL.  And also we dereferenced it on the
line before.  So this NULL check is pointless.  Delete it.
