Subject: [PATCH 04/11] ASoC: cs35l41: Create function for init array of Supplies
Date:   Tue, 23 Nov 2021 16:31:42 +0000
Message-ID: <20211123163149.1530535-5-tanureal@opensource.cirrus.com>
In-Reply-To: <20211123163149.1530535-1-tanureal@opensource.cirrus.com>

MIME-Version: 1.0

Precedence: bulk

Both ASoC and HDA system have to initialize the arrays of supplies
in the same way, so create a function for that in shared code
