Subject: [QUEUED v20160212 01/19] stm class: Use a signed return type for stm_find_master_chan
Date: Fri, 12 Feb 2016 19:00:17 +0200 [thread overview]
Message-ID: <1455296435-17362-2-git-send-email-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <1455296435-17362-1-git-send-email-alexander.shishkin@linux.intel.com>
From: Lucas Tanure <tanure@linux.com>
The return type "unsigned int" was used by the stm_find_master_chan function
despite of the aspect that it will eventually return a negative error code.
Done with the help of Coccinelle.
