Subject: gpio: omap: use devm_irq_alloc_descs()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2ed36f30139f773e3c99eeca2307b7a6596f4b90;p=linux.git

gpio: omap: use devm_irq_alloc_descs()

This driver never frees the allocated interrupt descriptors. Fix it by
using a resource managed variant of irq_alloc_descs().
