From d3601e56cf64a3f2df6f6380cccb3644274406e2 Mon Sep 17 00:00:00 2001 From: Cyril Roelandt Date: Wed, 12 Dec 2012 01:24:54 +0100 Subject: [PATCH] spi/sh-hspi: fix return value check in hspi_probe(). 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.
