Input: ep93xx_keypad - pass correct pointer to free_irq()

Browse Source 
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>

request_irq(..., devid)

free_irq@p(..., devid)

position p != r2.p;
