Subject[PATCH 1/4] net: rfkill: gpio: remove unused and obsolete platform parameters
Date
After upgrading to descriptor based gpios, the gpio numbers
are not used anymore. The power_clk_name and the platform
specific setup and close hooks are not used by anybody, and
we should not encourage use of such things, so removing them.
