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

Pull i2c fixes from Wolfram Sang:
 "A few bugfixes and one PCI ID addition from I2C"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: i801: add Intel Lewisburg device IDs
  i2c: fix wakeup irq parsing
  i2c: xiic: Prevent concurrent running of the IRQ handler and __xiic_start_xfer()
  i2c: Revert "i2c: xiic: Do not reset controller before every transfer"
  i2c: imx: fix a compiling error
