Subject: [PATCH] clk: use i2c_match_id and simple i2c probe
Date:   Thu, 24 Mar 2022 17:59:04 +0100
Message-Id: <20220324165904.538861-1-steve@sk2.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
