Subject: [PATCH] regulator: Make max8997_get_voltage_register always return correct register
Date: Tue, 13 Mar 2012 11:22:41 +0800 [thread overview]
Message-ID: <1331608961.11322.5.camel@phoenix> (raw)
Check max8997->buck[1|2|5]_gpiodvs status in max8997_get_voltage_register
and return correct register accordingly.
