[PATCHv3,2/5] net: rfkill: gpio: remove unused and obsolete platform parameters

Commit Message

Heikki Krogerus April 1, 2014, 2:02 p.m. UTC

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.
