Config-only test, same scope as yours - not booted with a kernel built this way. Starting config: linux-ptl 7.2.3-arch1-1, the Panther Lake kernel Omarchy ships, taken from /lib/modules/.../build/.config. It has CONFIG_MEDIA_HIDE_ANCILLARY_SUBDRV=y, no CONFIG_EXPERT, and no VIDEO_INTEL_CVS line at all. Run on a vanilla v7.2.4 tree. linux-ptl does not touch the files involved: drivers/media/{i2c,pci/intel,pci/intel/ipu6}/Kconfig, drivers/staging/media/ipu7/Kconfig and drivers/media/i2c/cvs/Kconfig are byte-identical to vanilla, as is every other Kconfig under drivers/media. before: make olddefconfig -> no VIDEO_INTEL_CVS line after: make olddefconfig -> CONFIG_VIDEO_INTEL_CVS=m Diffing the two generated configs shows exactly one changed line, the added CONFIG_VIDEO_INTEL_CVS=m. Nothing else moves. Worth noting for the stable case you mention: this is a distro kernel that already carries IPU_BRIDGE=m and VIDEO_INTEL_IPU7=m, so it is precisely the configuration whose bridge routes to a driver it cannot currently build.
