Subject: [PATCH 09/11] regulator: pv88080: Convert to use regulator_set/get_current_limit_regmap
Date:   Thu, 28 Feb 2019 21:40:20 +0800
Message-Id: <20190228134022.32625-10-axel.lin@ingics.com>
In-Reply-To: <20190228134022.32625-1-axel.lin@ingics.com>
References: <20190228134022.32625-1-axel.lin@ingics.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use regulator_set/get_current_limit_regmap helpers to save some code.
