Hub driver will try to disable a USB3 device twice at logical disconnect,
racing with xhci_free_dev() callback from the first port disable.
This can be triggered with "udisksctl power-off --block-device "
or by writing "1" to the "remove" sysfs file for a USB3 device
in 4.17-rc4.

One more xhci fix for 4.17.

Revealed a race by causing a NULL pointer dereference regression in
4.17-rc4 and stable. Fix it.

This patch adds role switch support for R-Car SoCs into the USB
3.0 peripheral driver. Some R-Car SoCs (e.g. R-Car H3) have USB
3.0 dual-role device controller which has the USB 3.0 xHCI host
and Renesas USB 3.0 peripheral.
Unfortunately, the mode change register contains the USB 3.0 peripheral

I still marked this patch set as "RFC". I would like to know whether
this way is good or not.

It has been observed that writing 0xF2 to the power register while it
reads as 0xF4 results in the register having the value 0xF0, i.e. clearing

usbip_host updates device status without holding lock from stub probe,
disconnect and rebind code paths. When multiple requests to import a
device are received, these unprotected code paths step all over each
other and drive fails with NULL-ptr deref and use-after-free errors.
