Subject: [PATCH] usb: typec: ucsi: add DRM_BRIDGE dependencies
Date: Fri, 25 Apr 2025 13:30:21 +0200 [thread overview]
Message-ID: <20250425113025.1718145-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
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.
Fixes: 00327d7f2c8c ("usb: typec: ucsi: add Huawei Matebook E Go ucsi driver")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202504140319.dgpbDOJZ-lkp@intel.com/
