Subject[PATCH 3.18 20/47] mmc: host: omap_hsmmc: checking for NULL instead of IS_ERR()
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>


[ Upstream commit ec5ab8933772c87f24ad62a4a602fe8949f423c2 ]

devm_pinctrl_get() returns error pointers, it never returns NULL.

Fixes: 455e5cd6f736 ("mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335x")
