From 03c835f498b540087244a6757e87dfe7ef10999b Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sun, 26 Feb 2023 23:26:52 +0100 Subject: i2c: Switch .probe() to not take an id parameter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type") introduced a new probe callback to convert i2c init routines to not take an i2c_device_id parameter. Now that all in-tree drivers are converted to the temporary .probe_new() callback, .probe() can be modified to match the desired prototype. Now that .probe() and .probe_new() have the same semantic, they can be defined as members of an anonymous union to save some memory and simplify the core code a bit.
