07606bfc73 gpio: lynxpoint: remove unnecessary platform_set_drvdata() 
The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

1d09aaa6a3 gpio/lynxpoint: add chipset gpio driver. 
Add gpio support for Intel Lynxpoint chipset.

Lynxpoint supports 94 gpio pins which can generate interrupts.
Driver will fail requests for pins that are marked as owned by ACPI, or
set in an alternate mode (non-gpio).
