Merge tag 'i2c-for-6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "This marks the end of a transition to let I2C have the same probe semantics as other subsystems. Uwe took care that no drivers in the current tree nor in -next use the deprecated .probe call. So, it is a good time to switch to the new, standard semantics now. There is also a regression fix: - regression fix for the notifier handling of the I2C core - final coversions of drivers away from deprecated .probe - make .probe_new the standard probe and convert I2C core to use it * tag 'i2c-for-6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: dev: Fix bus callback return values i2c: Convert drivers to new .probe() callback i2c: mux: Convert all drivers to new .probe() callback i2c: Switch .probe() to not take an id parameter media: i2c: ov2685: convert to i2c's .probe_new() media: i2c: ov5695: convert to i2c's .probe_new() w1: ds2482: Convert to i2c's .probe_new() serial: sc16is7xx: Convert to i2c's .probe_new() mtd: maps: pismo: Convert to i2c's .probe_new() misc: ad525x_dpot-i2c: Convert to i2c's .probe_new()
