From: Necip Fazil Yildiran <fazilyildiran@xxxxxxxxx> [ Upstream commit 4b53a3c72116118d86fab4112277e1dc4edf273c ] When OCXL is enabled and HOTPLUG_PCI is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [y]: - OCXL [=y] && PPC_POWERNV [=y] && PCI [=y] && EEH [=y] The reason is that OCXL selects HOTPLUG_PCI_POWERNV without depending on or selecting HOTPLUG_PCI while HOTPLUG_PCI_POWERNV is subordinate to HOTPLUG_PCI. HOTPLUG_PCI_POWERNV is a visible symbol with a set of dependencies. Selecting it will lead to overlooking its other dependencies as well. Let OCXL depend on HOTPLUG_PCI_POWERNV instead to avoid Kbuild issues.
