[PATCH] irq-devres: fix failure path of devm_request_irq()
devres should be deallocated with devres_free() not kfree(). This bug corrupts slab on IRQ request failure. Fix it. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Greg KH <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
