[ Upstream commit d8a79c03054911c375a2252627a429c9bc4615b6 ]
The Kconfig symbol depended on MMU but was dropped by the 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 COMPILE_TEST is set but that could lead to unmet direct dependencies
and linking errors.
Prevent a kconfig warning when MMU is not enabled by making
DRM_HISI_HIBMC depend on MMU.
WARNING: unmet direct dependencies detected for DRM_TTM
Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && MMU [=n]
Selected by [m]:
- DRM_TTM_HELPER [=m] && HAS_IOMEM [=y] && DRM [=m]
- DRM_HISI_HIBMC [=m] && HAS_IOMEM [=y] && DRM [=m] && PCI [=y] && (ARM64 || COMPILE_TEST [=y])
Fixes: acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu")
