Merge tag 'i2c-for-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "i2c core removes an argument from the i2c_mux_add_adapter() call to further deprecate class based I2C device instantiation. All users are converted, too. Other that that, Andi collected a number if I2C host driver patches.
