Input: pmic8xxx-pwrkey - pass correct pointer to free_irq()
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:
<smpl>
@r1@
type T;
T devid;
@@
request_irq(..., devid)
@r2@
type r1.T;
T devid;
position p;
@@
free_irq@p(..., devid)
@@
position p != r2.p;

*free_irq@p(...)
