Merge tag 'pinctrl-v4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij: "This is a first set of pin control fixes for the v4.3 series. Nothing special to say, business as usual. - Some IS_ERR() fixes from Julia Lawall. I always wanted the compiler to catch these but error pointers by nailing them as an err pointer intrinsic type or something seem to be a "no can do". In any case, cocinelle is obviously up to the task, better than bugs staying around. - Better error handling for NULL GPIO chips. - Fix a compile error from the big irq desc refactoring. I'm surprised the fallout wasn't bigger than this" * tag 'pinctrl-v4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: samsung: s3c24xx: fix syntax error pinctrl: core: Warn about NULL gpio_chip in pinctrl_ready_for_gpio_range() pinctrl: join lines that can be a single line within 80 columns pinctrl: digicolor: convert null test to IS_ERR test pinctrl: qcom: ssbi: convert null test to IS_ERR test
