Subject: [PATCH 03/12] crypto: caam - check irq_of_parse_and_map for errors
Date: Tue, 3 Sep 2019 19:35:06 -0700 [thread overview]
Message-ID: <20190904023515.7107-4-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190904023515.7107-1-andrew.smirnov@gmail.com>
Irq_of_parse_and_map will return zero in case of error, so add a error
check for that.
