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")
