Subject: [PATCH net-next v3 6/6] devlink: add missing NULL checks for devlink ops
Date: Fri, 22 Feb 2019 14:07:57 -0800 [thread overview]
Message-ID: <20190222220758.7117-7-jakub.kicinski@netronome.com> (raw)
In-Reply-To: <20190222220758.7117-1-jakub.kicinski@netronome.com>
Commit 76726ccb7f46 ("devlink: add flash update command") and
commit 2d8dc5bbf4e7 ("devlink: Add support for reload")
access devlink ops without NULL-checking. Add the missing checks.
Note that all drivers currently implementing devlink pass non-NULL
ops, so this is not a problem.
