+Subject: genirq: Release resources in __setup_irq() error path
+
+From: Heiner Kallweit <hkallweit1@gmail.com>
+
+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.
+
+Fixes: c1bacbae8192 ("genirq: Provide irq_request/release_resources chip callbacks")
