From 862de70c12bb6227943e155251c75e7fa4558068 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 11 Aug 2011 15:21:00 +0800 Subject: mfd: Make sure to request twl6030 IRQ before using the irq_num I was trying to fix the error handling part because in the case of request_irq failure, it should call kthread_stop instead of free_irq. But it seems more reasonable to do request_irq before calling kthread_run.
