Subject: [PATCH 4.4 65/86] Input: xpad - avoid using __set_bit() for capabilities

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit a01308031c2647ed5f1c845104b73a8820a958a9 ]

input_set_capability() and input_set_abs_param() will do it for you.
