Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c fixes from Wolfram Sang: "We had various reports of problems with deferred probing in the I2C subsystem, so this pull requst is a little bigger than usual. Most issues should be addressed now so devices will be found correctly. A few ususal driver bugfixes are in here, too" * 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: i2c-mux-pinctrl: use deferred probe when adapter not found i2c: i2c-arb-gpio-challenge: use deferred probe when adapter not found i2c: i2c-mux-gpio: use deferred probing i2c: i2c-mux-gpio: don't ignore of_get_named_gpio errors i2c: omap: Clear ARDY bit twice i2c: Not all adapters have a parent i2c: i2c-stu300: replace platform_driver_probe to support deferred probing i2c: i2c-mxs: replace platform_driver_probe to support deferred probing i2c: i2c-imx: replace platform_driver_probe to support deferred probing i2c: i2c-designware-platdrv: replace platform_driver_probe to support deferred probing
