Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull second i2c update from Wolfram Sang:
 "As promised, here is my 2nd pull request for I2C, containing:

   - removal of the attach_adapter callback, converting its last user

   - removal of any __deprecated usage within I2C

   - one email address update

   - some SPDX conversion"

* 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: don't use any __deprecated handling anymore
  i2c: use SPDX identifier for Renesas drivers
  i2c: ocores: update my email address
  i2c: remove deprecated attach_adapter callback
  macintosh: therm_windtunnel: drop using attach_adapter
