commit: 57d13370cfaf6017c68981e66ff5b3bf20a2705c From: Rafael J. Wysocki <[email protected]> Date: Tue, 13 Mar 2012 22:40:14 +0100 Subject: PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on()
Make the MTU2 clocksource driver mark its device as "always on" using pm_genpd_dev_always_on() to protect it from surprise power removals. Signed-off-by: Rafael J.
