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

Pull i2c fixes from Wolfram Sang:
 "Here are some bugfixes from I2C, especially removing a wrongly
  displayed error message for all i2c muxes"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: xgene: Set ACPI_COMPANION_I2C
  i2c: mv64xxx: don't override deferred probing when getting irq
  i2c: mux: only print failure message on error
  i2c: mux: reg: rename label to indicate what it does
  i2c: mux: reg: put away the parent i2c adapter on probe failure
