From 698d692cd8854ccb6509633f0bdbea2a83c491b3 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Wed, 3 Apr 2024 15:36:10 -0500 Subject: [PATCH] hwmon: (ds1621) Remove use of i2c_match_id() The function i2c_match_id() is used to fetch the matching ID from the i2c_device_id table. This is often used to then retrieve the matching driver_data. This can be done in one step with the helper i2c_get_match_data(). This helper has a couple other benefits: * It doesn't need the i2c_device_id passed in so we do not need to have that forward declared, allowing us to remove those or move the i2c_device_id table down to its more natural spot with the other module info. * It also checks for device match data, which allows for OF and ACPI based probing. That means we do not have to manually check those first and can remove those checks.
