Subject: irqchip/irq-mvebu-pic: Make use of the helper function devm_platform_ioremap_resource()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bacdbd710de553c9c998235231139f0921a5750c;p=linux.git

irqchip/irq-mvebu-pic: Make use of the helper function devm_platform_ioremap_resource()

Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately
