From: René van Dorst Date: Thu, 19 Jul 2018 10:55:55 +0000 (+0200) Subject: treewide: convert gpio-export to platform driver X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0ae9396556584db2dac73364af44758a5ccf4873;p=openwrt%2Fstaging%2Fxback.git treewide: convert gpio-export to platform driver Without this patch you will get an error "gpio-export probe deferral not supported" when you try to export i2c expander gpio pins. gpio-export is probed long before i2c-bus and i2c expander are created and it doesn't retry it so none pins are exported.
