Subject: [PATCH] drm/panel: nt37801: select CONFIG_DRM_DISPLAY_DSC_HELPER
Date: Fri, 23 May 2025 14:11:22 +0200 [thread overview]
Message-ID: <20250523121127.2269693-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The newly added driver uses the DSC helper module, but does not
select its Kconfig symbol, so configurations are possible that
cause a link failure:
ERROR: modpost: "drm_dsc_pps_payload_pack" [drivers/gpu/drm/panel/panel-novatek-nt37801.ko] undefined!
Fixes: 4fca6849864d ("drm/panel: Add Novatek NT37801 panel driver")

Say Y here if you want to enable support for Novatek NT37801 (or
