Additionally, this fails on the Snapdragon SC8280XP based Thinkpad X13s with 6.1-rc4 (and rc5), however, unlike Javier's setup, I *do* have CONFIG_SC_GPUCC_SC8280XP=y, so it's already built in to the kernel.  Additionally, all DRM options =y, except for CONFIG_DRM_GEM_HELP=m and CONFIG_DRM_DISPLAY_CONNECTOR=m. I am hoping to find some time tonight after work to also test on my SDM850 based Lenovo Yoga C630, as I believe my previous testing of 6.1 may have been hitting this but I did not have time to dig into what was going on there. -- steev
