Subject: [PATCH] drm/panel: r66451: select CONFIG_DRM_DISPLAY_DP_HELPER
Date: Wed, 19 Jul 2023 15:09:21 +0200 [thread overview]
Message-ID: <20230719130940.659837-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The newly added driver only builds when DRM_DISPLAY_DP_HELPER is enabled:
x86_64-linux-ld: drivers/gpu/drm/panel/panel-visionox-r66451.o: in function `visionox_r66451_enable':
panel-visionox-r66451.c:(.text+0x105): undefined reference to `drm_dsc_pps_payload_pack'
Select both CONFIG_DRM_DISPLAY_DP_HELPER and CONFIG_DRM_DISPLAY_HELPER to
ensure the helper function is always available.
Fixes: a6dfab2738fc2 ("drm/panel: Add driver for Visionox r66451 panel")
