Subject: mailbox: bcm2835: Make use of the helper function devm_platform_ioremap_resource()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ea9c66b1410ec9751a0b523d2fc55714c5bf711a;p=linux.git

mailbox: bcm2835: 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
