Subject: [PATCH 2/2] regulator: max5970: Rename driver and remove wildcard
Date:   Thu, 27 Apr 2023 12:22:54 +0200
Message-Id: <20230427102254.3864526-2-Naresh.Solanki@9elements.com>
In-Reply-To: <20230427102254.3864526-1-Naresh.Solanki@9elements.com>
References: <20230427102254.3864526-1-Naresh.Solanki@9elements.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The previous version of this driver included wildcards in file names and
descriptions. This patch renames the driver to only support MAX5970 and
MAX5978, which are the only chips that the driver actually supports.
