Subject: [PATCH] [v2] drm/panel: s6e3ha8: select CONFIG_DRM_DISPLAY_DSC_HELPER

From: Arnd Bergmann <arnd@...db.de>

The new driver needs the dsc helper code to be available:

x86_64-linux-ld: vmlinux.o: in function `s6e3ha8_amb577px01_wqhd_prepare':
panel-samsung-s6e3ha8.c:(.text+0x16b1e65): undefined reference to `drm_dsc_pps_payload_pack'

Select it from Kconfig as we do for other similar drivers.

Fixes: 779679d3c164 ("drm/panel: Add support for S6E3HA8 panel driver")
