From: Peter Griffin Date: Wed, 13 Apr 2016 16:58:44 +0000 (+0300) Subject: usb: host: xhci-plat: Make enum xhci_plat_type start at a non zero value X-Git-Tag: Ubuntu-5.2.0-15.16~9377^2~4 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=f9a85f6e61c695daeb427dfc6c1d5a279654207b;p=mirror_ubuntu-eoan-kernel.git usb: host: xhci-plat: Make enum xhci_plat_type start at a non zero value 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.
