From: Arnd Bergmann <a...@arndb.de>
The imx display drivers use the new bridge connector helpers but don't
explicitly select CONFIG_DRM_DISPLAY_HELPER, leading to a link failure
in rare configurations:
ld.lld-20: error: undefined symbol: drm_bridge_connector_init
>>> referenced by imx-ldb.c
>>> drivers/gpu/drm/imx/ipuv3/imx-ldb.o:(imx_ldb_bind) in archive
>>> vmlinux.a
>>> referenced by parallel-display.c
>>> drivers/gpu/drm/imx/ipuv3/parallel-display.o:(imx_pd_bind) in
>>> archive vmlinux.a
Move DRM_BRIDGE_CONNECTOR out of the DRM_DISPLAY_HELPER block and
instead select that symbol indirectly.
Fixes: f94b9707a1c9 ("drm/imx: parallel-display: switch to imx_legacy_bridge /
drm_bridge_connector")
