Yeal already applied it for fixes. Added the Fixes: tag now. > But your current patch "[PATCH 092/182] pinctrl: bcm2835: use gpiochip data > pointer" seems to conflict with my? No problem. I will merge the next release candidate into the GPIO tree and fix the conflicts after this fix is merged. Fixing conflicts is all subsystem maintainers do some days :D Yours, Linus Walleij -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
