Input: gpio_mouse - rename platform data variables
Use more appropriate names for the "platform data" which is now just a simple state container for the GPIO mouse. Acked-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
