Subject: [PATCH v2 1/7] ASoC: ak*: use i2c_match_id and simple i2c probe
Date:   Fri, 15 Apr 2022 18:06:07 +0200
Message-Id: <20220415160613.148882-2-steve@sk2.org>
In-Reply-To: <20220415160613.148882-1-steve@sk2.org>

As part of the ongoing i2c transition to the simple probe
("probe_new"), this patch uses i2c_match_id to retrieve the
driver_data for the probed device. The id parameter is thus no longer
necessary and the simple probe can be used instead.
