Subject: [PATCH 5/5] spi: fix return value check in hspi_probe().
Date: Wed, 12 Dec 2012 01:24:54 +0100 [thread overview]
Message-ID: <1355271894-5284-6-git-send-email-tipecaml@gmail.com> (raw)
In-Reply-To: <1355271894-5284-1-git-send-email-tipecaml-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
According to its documentation, clk_get() returns a "valid IS_ERR() condition
containing errno", so we should call IS_ERR() rather than a NULL check.
