Subject: pwm: mxs: Use devm_platform_ioremap_resource() to simplify code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a315614b68993318f6913cc28b9b4e472ebbdf26;p=openwrt%2Fstaging%2Fblogic.git

pwm: mxs: Use devm_platform_ioremap_resource() to simplify code

Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.
