From 707188f5f2421a304324e6ef3aaf4413cfab0f3d Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Wed, 31 May 2017 18:06:56 +0200 Subject: irq/generic-chip: Provide irq_free_generic_chip() Currently there's no way for users of irq_alloc_generic_chip() to free the allocated memory other than calling kfree() manually on the returned pointer. This may lead to errors if the internals of irq_alloc_generic_chip() ever change. Provide a routine to free the generic chip.
