From 1cb7b43f6796ad0bc62669fa52d1005916911d27 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sat, 8 Mar 2014 11:55:29 +0800 Subject: regulator: pbias: Fix is_enabled callback implementation The is_enabled implementation is wrong in some cases: e.g. for pbias_mmc_omap5: enable_mask is : BIT(27) | BIT(25) | BIT(26) However, pbias_regulator_enable() only sets BIT(27) | BIT(26) bits. So is_enabled callback will always return false in this case. Fix the logic to compare the register value with info->enable rather than info->enable_mask.
