As with several other panel drivers, this fails to link without the DP
helper library:
ld: drivers/gpu/drm/panel/panel-raydium-rm692e5.o: in function `rm692e5_prepare':
panel-raydium-rm692e5.c:(.text+0x11f4): undefined reference to `drm_dsc_pps_payload_pack'
Select the same symbols that the others already use.

Say Y here if you want to enable support for Raydium RM692E5-based
display panels, such as the one found in the Fairphone 5 smartphone.

Will apply once drm-misc-next-fixes is synced with the last drm-misc-next PR for v6.7.

Sounds like this helper should be extracted from DP specific code
in the future though, no?

Hi Neil,
I think this patch is still pending, I don't see it in linux-next.
It was also reported by a buildbot today
https://lore.kernel.org/lkml/[email protected]/
