From 5434b203156ef245b7847128c446c5b54f12a6d4 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 14 Mar 2014 18:22:09 +0100 Subject: ata: ahci_platform: fix devm_ioremap_resource() return value checking devm_ioremap_resource() returns a pointer to the remapped memory or an ERR_PTR() encoded error code on failure. Fix the check inside ahci_platform_get_resources() accordingly. Also while at it remove a needless line break.
