[PATCHv5 10/11] TEMP: OMAP3: pm: disable / enable PRCM chain interrupts during wakeup from suspend

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This prevents system hang while attempting to access suspended console. Should
most likely be fixed with proper console locking.
