uio: don't free irq that was not requested UIO base driver should only free_irq that it has requested. UIO supports drivers without interrupts (irq == 0) or custom handlers. This fixes warnings like: WARNING: CPU: 1 PID: 5478 at kernel/irq/manage.c:1244 __free_irq+0xa9/0x1e0() Trying to free already-free IRQ 0 Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
