Subject: [PATCH] drm/panel: fix novatek-nt36536 dependencies
Date: Fri, 25 Sep 2026 15:01:00 +0200 [thread overview]
Message-ID: <20260925130125.3897046-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The recently added driver requires access to DSC helper code
and fails to link without that:
ld.lld: error: undefined symbol: drm_dsc_pps_payload_pack
>>> referenced by panel-novatek-nt36536.c:109 (/home/arnd/arm-soc/drivers/gpu/drm/panel/panel-novatek-nt36536.c:109)
>>> drivers/gpu/drm/panel/panel-novatek-nt36536.o:(novatek_prepare) in archive vmlinux.a
Add the usual Kconfig dependency.
Fixes: 75a5dbd1f4f7 ("drm/panel: Add Novatek NT36536 panel driver")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Say Y here if you want to enable support for Novatek NT36536-based
