Subject[PATCH 1/3] regulator: pbias: Fix is_enabled callback implementation
From
Date
The is_enabled implementation is wrong in some cases:
e.g. for pbias_mmc_omap5: emable_mask is : BIT(27) | BIT(25) | BIT(26)
However, pbias_regulator_enable() only sets BIT(26) | BIT(22) 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.
