[PATCH] usb: typec: ucsi: add DRM_BRIDGE dependencies
From: Arnd Bergmann
Date: Fri Apr 25 2025 - 07:31:23 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
Selecting CONFIG_DRM_AUX_HPD_BRIDGE is not allowed when its dependencies
are not met:
WARNING: unmet direct dependencies detected for DRM_AUX_HPD_BRIDGE
Depends on [n]: HAS_IOMEM [=y] && DRM [=n] && DRM_BRIDGE [=n] && OF [=n]
Selected by [m]:
- UCSI_HUAWEI_GAOKUN [=m] && USB_SUPPORT [=y] && TYPEC [=y] && TYPEC_UCSI [=m] && EC_HUAWEI_GAOKUN [=m]
ERROR: modpost: "drm_bridge_hpd_notify" [drivers/gpu/drm/bridge/aux-hpd-bridge.ko] undefined!
ERROR: modpost: "devm_drm_bridge_add" [drivers/gpu/drm/bridge/aux-hpd-bridge.ko] undefined!
Add the same dependencies for the new UCSI_HUAWEI_GAOKUN driver to ensure
it always builds cleanly.
