Input: auo_pixcir_ts - keep own pointer to platform_data

A patch from »Input: auo_pixcir_ts - add devicetree support« in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Fri, 22 Feb 2013 23:27:37 +0100

Commit-Message

When supporting devicetree the platformdata may not necessarily come from the dev but may be generated in the driver instead. Therefore keep the pointer in the driver struct instead of using dev.platform_data. Signed-off-by: Heiko Stuebner <heiko@...>
