From 4d1518f5668ef1b3dff6c3b30fa761fe5573cdaa Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 21 Jun 2011 23:24:33 +0200 Subject: PM / Runtime: Handle clocks correctly if CONFIG_PM_RUNTIME is unset Commit 85eb8c8d0b0900c073b0e6f89979ac9c439ade1a (PM / Runtime: Generic clock manipulation rountines for runtime PM (v6)) converted the shmobile platform to using generic code for runtime PM clock management, but it changed the behavior for CONFIG_PM_RUNTIME unset incorrectly. Specifically, for CONFIG_PM_RUNTIME unset pm_runtime_clk_notify() should enable clocks for action equal to BUS_NOTIFY_BIND_DRIVER and it should disable them for action equal to BUS_NOTIFY_UNBOUND_DRIVER (instead of BUS_NOTIFY_ADD_DEVICE and BUS_NOTIFY_DEL_DEVICE, respectively). Make this function behave as appropriate. Signed-off-by: Rafael J.
