Subject: [PATCH] drm: bridge: fix unmet dependency on DRM_KMS_HELPER for DRM_PANEL_BRIDGE
Date: Mon, 25 Oct 2021 13:42:02 -0400 [thread overview]
Message-ID: <20211025174202.32396-1-julianbraha@gmail.com> (raw)
When DRM_CHIPONE_ICN6211 is selected, and DRM_KMS_HELPER is not selected,
Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for DRM_PANEL_BRIDGE
Depends on [n]: HAS_IOMEM [=y] && DRM_BRIDGE [=y] && DRM_KMS_HELPER [=n]
Selected by [y]:
- DRM_CHIPONE_ICN6211 [=y] && HAS_IOMEM [=y] && DRM [=y] && DRM_BRIDGE [=y] && OF [=y]
This is because DRM_CHIPONE_ICN6211 selects DRM_PANEL_BRIDGE
without depending on or selecting DRM_KMS_HELPER,
despite DRM_PANEL_BRIDGE depending on DRM_KMS_HELPER.
This unmet dependency bug was detected by Kismet,
a static analysis tool for Kconfig.
Please advise if this is not the appropriate solution.
Fixes: ce517f18944e ("drm: bridge: Add Chipone ICN6211 MIPI-DSI to RGB bridge")
