If anyone has any objections, please let me know. ------------------ From: Peter Griffin commit f9a85f6e61c695daeb427dfc6c1d5a279654207b upstream. Otherwise generic-xhci and xhci-platform which have no data get wrongly detected as XHCI_PLAT_TYPE_MARVELL_ARMADA by xhci_plat_type_is(). This fixes a regression in v4.5 for STiH407 family SoC's which use the synopsis dwc3 IP, whereby the disable_clk error path gets taken due to wrongly being detected as XHCI_PLAT_TYPE_MARVELL_ARMADA and the hcd never gets added. I suspect this will also fix other dwc3 DT platforms such as Exynos, although I've only tested on STih410 SoC.
