3.16.7-ckt8 -stable review patch.  If anyone has any objections, please let me know.

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

From: Martin Vajnar <martin.vajnar at gmail.com>

commit a52d209336f8fc7483a8c7f4a8a7d2a8e1692a6c upstream.

Since the removal of CONFIG_REGULATOR_DUMMY option, the touchscreen stopped
working. This patch enables the "replacement" for REGULATOR_DUMMY and
allows the touchscreen to work even though there is no regulator for "vcc".
