The check for of_node_check_flag() was accidentally inverted, causing
i2c-demux-pinctrl to fail on the Koelsch development board:
i2c-demux-pinctrl i2c-mux1: failed to setup demux-adapter 0 (-19)
i2c-demux-pinctrl i2c-mux2: failed to setup demux-adapter 0 (-19)
i2c-demux-pinctrl i2c-mux3: failed to setup demux-adapter 0 (-19)
i2c-demux-pinctrl i2c-mux2: Failed to create device link (0x180) with e6ef0000.video
i2c-demux-pinctrl i2c-mux2: Failed to create device link (0x180) with e6ef1000.video
i2c-demux-pinctrl i2c-mux2: Failed to create device link (0x180) with hdmi-in
i2c-demux-pinctrl i2c-mux2: Failed to create device link (0x180) with hdmi-out
and anything relying on I2C connected to these muxes fails, too.
Also, loading the 25LC040 DT overlay on Ebisu using the out-of-tree
of-configfs now fails, too.
