Subject[PATCH] regulator: ab8500: Fix get_mode for shared mode regulators
From
Date
The special handling code for getting shared mode status is wrong
because it needs to check info->shared_mode->lp_mode_req for
both regulators that shared the same mode register.

In set_mode(), current code ensures we won't set mode to REGULATOR_MODE_IDLE
if only one of the regulator requests to set idle.

In get_mode(), we can just remove the special handling code for shared mode.
Read the register value always returns correct status no matter the regulator
has shared mode register or not.
