[PATCH] drivers/rtc/rtc-pl031.c: Pass correct pointer to free_irq()

From: Lars-Peter Clausen
Date: Mon May 20 2013 - 11:41:36 EST

free_irq() expects the same pointer that was passed to request_irq(), otherwise
the IRQ is not freed.

The issue was found using the following coccinelle script:

type T;
T devid;
request_irq(..., devid)

type r1.T;
T devid;
position p;
free_irq@p(..., devid)

position p != r2.p;
