Merge branch 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux

Pull i2c-embedded fixes from Wolfram Sang:
 "Some bugfixes for the "embedded" part of the I2C subsystem.  The fixes
  affect mostly drivers which have been largely reworked lately and
  where regressions appeared."

* 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux:
  i2c: tegra: protect suspend/resume callbacks with CONFIG_PM_SLEEP
  i2c: diolan-u2c: Fix master_xfer return code
  I2C: OMAP: xfer: fix runtime PM get/put balance on error
  i2c: nomadik: Add default configuration into the Nomadik I2C driver
