dtc has new checks for I2C buses. The sun9i-a80 dts file has a node named 'i2c' which causes a false positive warning. As the node is a RSB bus, correct the node name to be 'rsb' to fix the warnings. arch/arm/boot/dts/sun9i-a80-cubieboard4.dtb: Warning (i2c_bus_reg): /soc/i2c@8003400/codec@e89:reg: I2C address must be less than 10-bits, got "0xe89" arch/arm/boot/dts/sun9i-a80-cubieboard4.dtb: Warning (i2c_bus_reg): /soc/i2c@8003400/pmic@745:reg: I2C address must be less than 10-bits, got "0x745" arch/arm/boot/dts/sun9i-a80-optimus.dtb: Warning (i2c_bus_reg): /soc/i2c@8003400/codec@e89:reg: I2C address must be less than 10-bits, got "0xe89" arch/arm/boot/dts/sun9i-a80-optimus.dtb: Warning (i2c_bus_reg): /soc/i2c@8003400/pmic@745:reg: I2C address must be less than 10-bits, got "0x745" Cc: Maxime Ripard <maxime.ripard@xxxxxxxxxxx> Cc: Chen-Yu Tsai <wens@xxxxxxxx> Signed-off-by: Rob Herring <robh@xxxxxxxxxx> --- Please apply to the sub-arch tree.
