Subject: [PATCH 4.19 216/422] ARM: dts: sun9i: Fix I2C bus warnings

From: Rob Herring <robh@...nel.org>

[ Upstream commit 57a83c5222c1b5e7b3acc72c6e60fce00a38991a ]

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@...3400/codec@e89:reg: I2C address must be less than 10-bits, got "0xe89"
