And those two commits should be mentioned in the description. Maybe we can append the following two paragraphs to your commit message ? The Kconfig symbol depended on MMU but that was dropped by commit acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu") because it already had as a dependency ARM64 that already selects MMU. But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64 when the COMPILE_TEST is set but that could lead to unmet direct dependencies and linking errors. If you agree with the changes, I can do it before applying. Please let me know. -- Best regards, Javier Martinez Canillas Linux Engineering Red Hat
