Subject: [PATCH 3.16.y-ckt 012/183] hx4700: regulator: declare full constraints
3.16.7-ckt8 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Martin Vajnar <martin.vajnar@...il.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".
