[PATCH 06/26] Input: maplecontrol - simplify maple_device retrieval in open/close

[Dmitry Torokhov]

Instead of passing the dc_pad structure via platform_data to the
input device to retrieve the maple_device in open/close, store the
maple_device pointer in the input device's private data (drvdata)
and use input_get_drvdata() to retrieve it.

This allows us to remove the platform_data assignment in probe.
