[PATCH] Input: psxpad-spi - set driver data before use

[Linmao Li]

psxpad_spi_suspend() retrieves the controller state with
spi_get_drvdata(), but probe never stores it, so suspend dereferences a
NULL pointer. Store it during probe.

Fixes: 8be193c7b1f4 ("Input: add support for PlayStation 1/2 joypads connected via SPI")
