Pull i2c fixes from Wolfram Sang:
 "I2C has one buildfix, one ABBA deadlock fix, and three simple 'add ID'
  patches"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: exynos5: Fix possible ABBA deadlock by keeping I2C clock prepared
  i2c: cpm: Fix build break due to incompatible pointer types
  i2c: ismt: Add Intel DNV PCI ID
  i2c: xlp9xx: add support for Broadcom Vulcan
  i2c: rk3x: add support for rk3228

	  This driver enables support for the on-chip I2C interface of
	  the Broadcom XLP9xx/XLP5xx MIPS processors.
	  the Broadcom XLP9xx/XLP5xx MIPS and Vulcan ARM64 processors.

	  This driver can also be built as a module.  If so, the module will
