regulator: as3711: Fix valid min_uV/max_UV checking in as3711_bound_check
Below cases are supposed to be valid: min_uV == max_uV == info->max_uV min_uV == max_uV == rdev->desc->min_uV Don't return -EINVAL for above cases. This patch also includes below cleanups: - Use rdev_get_drvdata(rdev) instead of rdev->reg_data. - Remove unnecessary WARN_ON, it looks pointless.
