Subject: [PATCH 1/2] ASoC: ssm2518: drop support for platform data
Date:   Mon, 19 Sep 2022 19:58:03 -0700
Message-Id: <20220920025804.1788667-1-dmitry.torokhov@gmail.com>
MIME-Version: 1.0

Precedence: bulk

There are currently no users of this driver's platform data in the
mainline kernel, so let's drop it.

Newer devices should use DT, ACPI, or static software properties to
describe the hardware.
