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.
