Subject: genirq: Release resources in __setup_irq() error path

From: Heiner Kallweit <[email protected]>

commit fa07ab72cbb0d843429e61bf179308aed6cbe0dd upstream.

In case __irq_set_trigger() fails the resources requested via irq_request_resources() are not released.

Add the missing release call into the error handling path.
