Subject: power: reset: st-poweroff: Use of_device_get_match_data()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c05383b9074d72d244d3dea34832eeb725317575;p=thirdparty%2Fkernel%2Fstable.git

power: reset: st-poweroff: Use of_device_get_match_data()

Use of_device_get_match_data() to fetch the reset syscfg data directly
instead of open-coding an of_match_device() lookup.

This also lets the driver drop the of_device.h include.
