The panel-ilitek-ili9882t driver uses drm_dsc_pps_payload_pack() which
is provided by the DRM_DISPLAY_DSC_HELPER. Add the missing Kconfig
select to fix the following build error:
ERROR: modpost: "drm_dsc_pps_payload_pack" [drivers/gpu/drm/panel/panel-ilitek-ili9882t.ko] undefined!
Fixes: 65ce1f5834e9 ("drm/panel: ilitek-ili9882t: Switch Tianma TL121BVMS07 to DSC 120Hz mode")

Say Y if you want to enable support for panels based on the
Ilitek ILI9882t controller.

Thanks, this build failure has been annoying me for the past few days,
can confirm it works as described and the fix makes sense.

You applied to the wrong branch, it's supposed to be applied to drm-misc-next-fixes after rc6

Before applying to drm-misc-next, I tried to apply to drm-misc-next-
fixes, but the patch didn't apply to that branch (65ce1f5834e9 is not
there yet). With that, I decided to apply to drm-misc-next.

Please ask before and let me apply the changes, now the patch will be applied for v6.21...
when asked, the drm-misc maintainers would prepare the drm- misc-next-fixes for use to apply.
@maxime, thomas, what the right step now ?
