Hi Andrzej,
I had to revert the previous patch, so you should re-spin it entirely :
================================ After merging the drm-misc tree, today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/gpu/drm/radeon/radeon_connectors.c: In function 'radeon_add_legacy_connector': drivers/gpu/drm/radeon/radeon_connectors.c:2433:5: error: 'ddc' undeclared (first use in this function) ddc = &radeon_connector->ddc_bus->adapter; ^~~ drivers/gpu/drm/radeon/radeon_connectors.c:2433:5: note: each undeclared identifier is reported only once for each function it appears in
Caused by commit
bed7a2182de6 ("drm/radeon: Provide ddc symlink in connector sysfs directory")
I have used the drm-misc tree from next-20190731 for today. ==================================
