Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c fixes from Wolfram Sang: "Two I2C driver bugfixes. The 'VLLS mode support' patch should have been entitled 'reconfigure pinctrl after suspend' to make the bugfix more clear. Sorry, I missed that, yet didn't want to rebase" * 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: imx-lpi2c: add VLLS mode support i2c: i2c-cadence: Initialize configuration before probing devices
