| |
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(...) </smpl>
