It turns out my "mostly" was wrong in this matter. It's 4 out of 17 patches, which make the initialization in the same order as mine: drivers/gpio/gpio-max732x.c drivers/gpio/gpio-pca953x.c drivers/gpio/gpio-pcf857x.c drivers/gpio/gpio-adp5588.c while the rest of them does it in the order suggested by you: drivers/gpio/gpio-pci-idio-16.c drivers/gpio/gpio-pcie-idio-24.c drivers/gpio/gpio-104-idio-16.c drivers/gpio/gpio-104-dio-48e.c drivers/gpio/gpio-ws16c48.c drivers/gpio/gpio-rcar.c drivers/gpio/gpio-wcove.c drivers/pinctrl/pinctrl-amd.c drivers/gpio/gpio-crystalcove.c drivers/pinctrl/pinctrl-mcp23s08.c drivers/pinctrl/pinctrl-sx150x.c drivers/pinctrl/pinctrl-stmfx.c drivers/gpio/gpio-tc3589x.c Then, let's use the same order here as the most of the drivers do just for consistency. -Sergey > > -- > With Best Regards, > Andy Shevchenko
