Merge tag 'i2c-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:

 - 'remove' callback converted to return void. Big change with trivial
   fixes all over the tree. Other subsystems depending on this change
   have been asked to pull an immutable topic branch for this.

 - new driver for Microchip PCI1xxxx switch

 - heavy refactoring of the Mellanox BlueField driver

 - we prefer async probe in the i801 driver now

 - the rest is usual driver updates (support for more SoCs, some
   refactoring, some feature additions)
