Merge tag 'pinctrl-v4.11-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fix from Linus Walleij: "This late fix for pin control is hopefully the last I send this cycle. The problem was detected early in the v4.11 release cycle and there has been some back and forth on how to solve it. Sadly the proper fix arrives late, but at least not too late. An issue was detected with pin control on the Freescale i.MX after the refactorings for more general group and function handling. We now have the proper fix for this" * tag 'pinctrl-v4.11-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()
