-----------------------------------------------------------
commit f148b9f402ef002b57bcff3964d45abc8ffb6c3f upstream.
A Full-speed bulk USB audio device (DJ-Tech CTRL) with a invalid Maximum Packet Size of 4 causes a xHC "Parameter Error" at enumeration.
This is because valid Maximum packet sizes for Full-speed bulk endpoints are 8, 16, 32 and 64 bytes. Hosts are not required to support other values than these. See usb 2 specs section 5.8.3 for details.
The device starts working after forcing the maximum packet size to 8. This is most likely the case with other devices as well, so force the maximum packet size to a valid range.

-----------------------------------------------------------
commit 024d411e9c5d49eb96c825af52a3ce2682895676 upstream.
Intel hosts that need the XHCI_PME_STUCK_QUIRK flag should enable runtime pm by calling xhci_pme_acpi_rtd3_enable() before usb_hcd_pci_probe() calls pci_dev_run_wake(). Otherwise usage count for the device won't be decreased, and runtime suspend is prevented.
usb_hcd_pci_probe() only decreases the usage count if device can generate run-time wake-up events, i.e. when pci_dev_run_wake() returns true.
This issue was exposed by pci_dev_run_wake() change in commit 8feaec33b986 ("PCI / PM: Always check PME wakeup capability for runtime wakeup support") and should be backported to kernels with that change

-----------------------------------------------------------
commit cf0ee7c60c89641f6e4d1d3c7867fe32b9e30300 upstream.
xhci driver assumed that xHC controllers have at most one custom supported speed table (PSI) for all usb 3.x ports. Memory was allocated for one PSI table under the xhci hub structure.
Turns out this is not the case, some controllers have a separate "supported protocol capability" entry with a PSI table for each port. This means each usb3 roothub port can in theory support different custom speeds.
To solve this, cache all supported protocol capabilities with their PSI tables in an array, and add pointers to the xhci port structure so that every port points to its capability entry in the array.
When creating the SuperSpeedPlus USB Device Capability BOS descriptor for the xhci USB 3.1 roothub we for now will use only data from the first USB 3.1 capable protocol capability entry in the array. This could be improved later, this patch focuses resolving the memory leak.
