[PATCH] usb: typec: ucsi: huawei-gaokin: add DRM dependency

Posted by Arnd Bergmann 2 weeks, 1 day ago

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.
