Date: Fri, 16 Mar 2012 21:36:45 +0800 From: Axel Lin <axel.lin@...il.com> To: linux-kernel@...r.kernel.org Cc: Balaji Rao <balajirrao@...nmoko.org>, Lars-Peter Clausen <lars@...afoo.de>, Liam Girdwood <lrg@...com>, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH RFT 2/2] regulator: Convert pcf50633 to get_voltage_sel Convert pcf50633 to get_voltage_sel and then we can remove pcf50633_regulator_voltage_value function and move its implementation to pcf50633_regulator_list_voltage.
