drivers/gpu/drm/bridge/analogix/analogix-anx78xx.c:40:17: warning:
‘anx7808_i2c_addresses’ defined but not used [-Wunused-const-variable=]
static const u8 anx7808_i2c_addresses[] = {
The definition of above two data variables is included by the
macro CONFIG_OF, so we also include the data variable
definitions in the macro CONFIG_OF. And in addition the data
variable anx78xx_match_table is included in the macro CONFIG_OF,
so we add CONFIG_OF to the place where it is used.
Fixes: 5d97408e0d70 ("drm/bridge: move ANA78xx driver to analogix subdirectory")
