Subject: [char-misc-next 5/6] mei: rename mei_free_cb_private to mei_io_cb_free
Date: Tue, 9 Oct 2012 16:50:20 +0200 [thread overview]
Message-ID: <1349794221-8667-5-git-send-email-tomas.winkler@intel.com> (raw)
In-Reply-To: <1349794221-8667-1-git-send-email-tomas.winkler@intel.com>
1. cb_private was an old name that we depriacated in earlier
cleanups
2. we also group the funcion declaration with other _io_
functions
3. Don't check cb for NULL as mei_io_cb_free is NULL safe
