Subject: regulator: pbias: Fix is_enabled callback implementation
X-Git-Tag: omap-for-v3.16/pm-signed~55^2^2~1

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.
