Subject: [PATCH v4 01/12] ASoC: cs35l56: Move shared data into a common data structure
Date:   Thu, 1 Jun 2023 16:47:20 +0100
Message-ID: <20230601154731.3210572-2-rf@opensource.cirrus.com>

From: Simon Trimmer <simont@opensource.cirrus.com>

The ASoC and HDA drivers have structures that contain some of the same
information - instead of maintaining two locations for this data the
drivers should share a common data structure as this will enable common
utility functions to be created.

The first step is to move the location of these members in the ASoC
driver.

Changes since Mark acked V1:
- The 1-line fix for cs35l56_sdw_interrupt() has been squashed in.
  Mark's ack was conditional on this.
- There was an identical error calling devm_free_irq() in
  cs35l56_remove() which has been fixed in V4. As this is
  a small 1-line bugfix I've carried forward Mark's ack.
