-Subject: irqchip: Plug a OF node reference leak in platform_irqchip_probe()
-
-From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
-
-commit 9322d1915f9d976ee48c09d800fbd5169bc2ddcc upstream.
-
-platform_irqchip_probe() leaks a OF node when irq_init_cb() fails. Fix it
-by declaring par_np with the __free(device_node) cleanup construct.
-
-This bug was found by an experimental static analysis tool that I am
-developing.
-
-Fixes: f8410e626569 ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")
