4.9-stable review patch. If anyone has any objections, please let me know.

[ 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")
