From bc88f11baf5a7e6671eac6fe3131c087d71a646f Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 5 Dec 2014 20:23:06 +0000 Subject: [PATCH] spi/s3c64xx: Remove redundant runtime PM management The device already asks the core to hold a runtime PM reference while it is active so it is redundant to open code that in the driver itself.
