Subject: [PATCH 1/3] watchdog: cadence: Simplify with dev_err_probe()
Date: Tue, 1 Sep 2020 17:31:39 +0200 [thread overview]
Message-ID: <20200901153141.18960-1-krzk@kernel.org> (raw)
Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and the error value gets printed.
