Subject: [PATCH 2/5] Input: joystick/maplecontrol - drop unnecessary call to input_set_drvdata

Since there is no call to dev_get_drvdata() or input_get_drvdata(),
the call to input_set_drvdata() is unnecessary and can be dropped.

The conversion was done automatically using the following coccinelle
script.
