Subject: [PATCH] mmc: host: omap_hsmmc: checking for NULL instead of IS_ERR()
Date: Mon, 10 Apr 2017 16:54:17 +0300 [thread overview]
Message-ID: <20170410135417.GD1918@mwanda> (raw)
devm_pinctrl_get() returns error pointers, it never returns NULL.
Fixes: 455e5cd6f736 ("mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335x")
