Subject: [PATCH] usb: typec: ucsi: huawei-gaokin: add DRM dependency
Date: Thu, 4 Dec 2025 11:11:07 +0100 [thread overview]
Message-ID: <20251204101111.1035975-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Selecting DRM_AUX_HPD_BRIDGE is not possible from a built-in driver when
CONFIG_DRM=m:
WARNING: unmet direct dependencies detected for DRM_AUX_HPD_BRIDGE
Depends on [m]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && OF [=y]
Selected by [y]:
- UCSI_HUAWEI_GAOKUN [=y] && USB_SUPPORT [=y] && TYPEC [=y] && TYPEC_UCSI [=y] && EC_HUAWEI_GAOKUN [=y] && DRM_BRIDGE [=y] && OF [=y]
Add the same dependency we have in similar drivers to work around this.
Fixes: 00327d7f2c8c ("usb: typec: ucsi: add Huawei Matebook E Go ucsi driver")
