Subject: [PATCH] regulator: hi6421v600: Remove unneeded *pmic from struct hi6421_spmi_reg_info
Date:   Fri, 30 Apr 2021 16:55:55 +0800
Message-Id: <20210430085555.1127994-1-axel.lin@ingics.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use rdev->regmap instead of pmic->regmap.
With this change, hi6421_spmi_regulator_disable can be removed and use
regulator_disable_regmap instead.
