[PATCH 2/7] ARM: shmobile: R-Mobile: Consolidate rmobile_pd_suspend_*()

From: Geert Uytterhoeven
Date: Wed Nov 19 2014 - 10:59:25 EST


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().
