Subject: [PATCH] clk: fix return value check in clk_get
Date: Fri, 20 Jul 2012 16:36:37 +0300 [thread overview]
Message-ID: <1342791397-11732-1-git-send-email-pdeschrijver@nvidia.com> (raw)
of_clk_get_by_name returns an ERR_PTR on failure. Hence we should use IS_ERR()
and not just check for a non NULL value.
