Hey Julian,

Nice catch, this patch looks good to me. I've pushed it to drm-misc-next.

When DRM_TOSHIBA_TC358762 is enabled and DRM_KMS_HELPER is disabled, 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_TOSHIBA_TC358762 [=y] && HAS_IOMEM [=y] && DRM [=y] && DRM_BRIDGE [=y] && OF [=y]

This is because DRM_TOSHIBA_TC358762 selects DRM_PANEL_BRIDGE, without depending on or selecting DRM_KMS_HELPER, despite that config option depending on DRM_KMS_HELPER.
