From: Stefan Sørensen Date: Mon, 3 Feb 2014 14:54:09 +0000 (+0100) Subject: mtd: elm: Use correct check on return value of pm_runtime_get_sync X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a21552a6e8ab9d3bacd490f5b94a178ce4d661d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mtd: elm: Use correct check on return value of pm_runtime_get_sync The ELM driver incorrectly reagard any non-zero return value from pm_runtime_get_sync as an error, but it may return 1 if the device was already active. Fix to only error when return value is negative.
