drm/bridge: lt8713sx select CONFIG_CRC8

[PATCH] drm/bridge: lt8713sx select CONFIG_CRC8

Posted by Arnd Bergmann 2 weeks, 5 days ago

From: Arnd Bergmann <arnd@arndb.de>

CRC8 needs to be enabled for lt8713sx to build:

ld.lld-22: error: undefined symbol: crc8_populate_msb
>>> referenced by lontium-lt8713sx.c
>>>               drivers/gpu/drm/bridge/lontium-lt8713sx.o:(lt8713sx_probe) in archive vmlinux.a

Fixes: 4037c6adc1f9 ("drm/bridge: add support for lontium lt8713sx bridge driver")
