Input: twl4030_keypad - pass correct pointer to free_irq()
free_irq() expects the same pointer that was passed to request_threaded_irq(), otherwise the IRQ is not freed. The issue was found using the following coccinelle script: <smpl> @r1@ type T; T devid; @@ request_threaded_irq(..., devid) @r2@ type r1.T; T devid; position p; @@ free_irq@p(..., devid) @@ position p != r2.p; @@ *free_irq@p(...) </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
