Subject: [PATCH 3.19.y-ckt 244/251] HID: rmi: fix some harmless BIT() mistakes

3.19.8-ckt4 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@...cle.com>

commit af43c4086cf24c3eb74a968195351163750c82b6 upstream.

These defines are used like this:

	if (!(test_bit(RMI_STARTED, &hdata->flags)))

So the intent was to use bits 0, 1 and 2 but because of the extra BIT()
shifts we're actually using 1, 2 and 4.  It's harmless because it's done
consistently but static checkers will complain.

Fixes: 9fb6bf02e3ad ('HID: rmi: introduce RMI driver for Synaptics touchpads')
