Subject: [PATCH 3.16 059/212] power: supply: bq24190_charger: Call
 set_mode_host() on pm_resume()

3.16.44-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Liam Breck <liam@...workimprov.net>

commit e05ad7e0741ce0505e1df157c62b22b95172bb97 upstream.

pm_resume() does a register_reset() which clears charger host mode.

Fix by calling set_mode_host() after the reset.
