From e43ee86efb68808c8847de17e58f5427b006363c Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 14 Jan 2015 13:11:20 +0100 Subject: [PATCH] ARM: shmobile: R-Mobile: Consolidate rmobile_pd_suspend_*() Consolidate the identical rmobile_pd_suspend_*() routines that just return -EBUSY to prevent a PM domain from being powered down into a single rmobile_pd_suspend_busy().
