From 2fb30d1147c599f5657e8c62c862f9a0f58d9d99 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 12 Jun 2012 16:14:51 +0200 Subject: spi/pl022: enable runtime PM If we're gonna use runtime PM it's a pretty good idea to actually enable it in probe() and disable it in remove() too, so it gets used for real. Up until now we only fooled around with the reference count.
