ARM: dts: orion5x-lschl: Fix model name
Model name should be consistent with legacy device file, so that user can migrate their system from legacy device support to device-tree safely. Legacy device file is currently removed, but it can be found on 4.8 or previous version of linux: arch/arm/mach-orion5x/ls-chl-setup.c Fixes: f94f268979a2 ("ARM: dts: orion5x: convert ls-chl to FDT") Cc: Ashley Hughes <ashley.hughes@blueyonder.co.uk> Signed-off-by: Roger Shimizu <rogershimizu@gmail.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
