From: Arnd Bergmann <arnd@xxxxxxxx> 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.
