[PATCH] irq: generic-chip: provide irq_free_generic_chip()

[Bartosz Golaszewski]

Some users of irq_alloc_generic_chip() are modules which can be
removed (e.g. gpio-ml-ioh) but have no means of freeing the allocated
generic chip. Provide a function for that.

Eek, -ETOEARLY - forgot the kernel doc...

Disregard this patch.
