From: Martin Vajnar <martin.vajnar@gmail.com>
3.4.108-rc1 review patch. If anyone has any objections, please let me know.
------------------
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".
