While the original bindings that were superseeded by the YAML schemas didn't mention that phy-names was needed, it turns out that phy-names is required if phys is set according to phy/phy-bindings.txt. Let's add back those properties.

According to usb_ep_set_halt()'s description, __usbhsg_ep_set_halt_wedge() should return -EAGAIN if the IN endpoint has any queue or data. Otherwise, this driver is possible to cause just STALL without sending a short packet data on g_mass_storage driver, and then a few resetting a device happens on a host side during a usb enumaration.

The commit 97664a20 ("usb: renesas_usbhs: shrink spin lock area") had added a usbhsg_pipe_disable() calling into __usbhsg_ep_set_halt_wedge() accidentally. But, this driver should not call the usbhsg_pipe_disable() because the function discards all queues. So, this patch removes it.

After commit f7fac17c ("xhci: Convert xhci_handshake() to use readl_poll_timeout_atomic()"), ASMedia xHCI may fail to suspend. Although the algorithms are essentially the same, the old max timeout is (usec + usec * time of doing readl()), and the new max timeout is just usec, which is much less than the old one. Increase the timeout to make ASMedia xHCI able to suspend again.

The system can hit a deadlock if an xhci adapter breaks while initializing. The deadlock is between two threads: thread 1 is tearing down the adapter and is stuck in usb_unlocked_disable_lpm waiting to lock the hcd->handwidth_mutex. Thread 2 is holding this mutex (while still trying to add a usb device), but is stuck in xhci_endpoint_reset waiting for a stop or config command to complete. A reboot is required to resolve. It turns out when calling xhci_queue_stop_endpoint and xhci_queue_configure_endpoint in xhci_endpoint_reset, the return code is not checked for errors. If the timing is right and the adapter dies just before either of these commands get issued, we hang indefinitely waiting for a completion on a command that didn't get issued. This wasn't a problem before the following fix because we didn't send commands in xhci_endpoint_reset: commit f5249461 ("xhci: Clear the host side toggle manually when endpoint is soft reset") With the patch I am submitting, a duration test which breaks adapters during initialization (and which deadlocks with the standard kernel) runs without issue.

The driver would return with a nonzero open count in case the reset control request failed. This would prevent any further attempts to open the char dev until the device was disconnected.

The driver is using its struct usb_device pointer as an inverted disconnected flag, but was setting it to NULL before making sure all completion handlers had run. This could lead to a NULL-pointer dereference in a number of dev_dbg and dev_err statements in the completion handlers which relies on said pointer. Fix this by unconditionally stopping all I/O and preventing resubmissions by poisoning the interrupt URBs at disconnect and using a dedicated disconnected flag. This also makes sure that all I/O has completed by the time the disconnect callback returns.

Fix a potential deadlock if disconnect races with open. Since commit d4ead16f ("USB: prevent char device open/deregister race") core holds an rw-semaphore while open is called and when releasing the minor number during deregistration. This can lead to an ABBA deadlock if a driver takes a lock in open which it also holds during deregistration. This effectively reverts commit 78663ecc ("USB: disconnect open race in legousbtower") which needlessly introduced this issue after a generic fix for this race had been added to core by commit d4ead16f ("USB: prevent char device open/deregister race").

The "run_isr" flag is used for preventing the driver from calling the interrupt service routine in its runtime resume callback when the driver is expecting completion to a command, but what that basically does is that it hides the real problem. The real problem is that the controller is allowed to suspend in the middle of command execution. As a more appropriate fix for the problem, using autosuspend delay time that matches UCSI_TIMEOUT_MS (5s). That prevents the controller from suspending while still in the middle of executing a command. This fixes a potential deadlock. Both ccg_read() and ccg_write() are called with the mutex already taken at least from ccg_send_command(). In ccg_read() and ccg_write, the mutex is only acquired so that run_isr flag can be set.

Drop the redundant disconnect mutex which was introduced after the open-disconnect race had been addressed generally in USB core by commit d4ead16f ("USB: prevent char device open/deregister race"). Specifically, the rw-semaphore in core guarantees that all calls to open() will have completed and that no new calls to open() will occur after usb_deregister_dev() returns. Hence there is no need use the driver data as an inverted disconnected flag. Signed-off-by:

Make sure to stop all I/O on disconnect by adding a disconnected flag which is used to prevent new I/O from being started and by stopping all ongoing I/O before returning.

According to Greg KH, it has been generally agreed that when a USB driver encounters an unknown error (or one it can't handle directly), it should just give up instead of going into a potentially infinite retry loop. The three codes -EPROTO, -EILSEQ, and -ETIME fall into this category. They can be caused by bus errors such as packet loss or corruption, attempting to communicate with a disconnected device, or by malicious firmware. Nowadays the extent of packet loss or corruption is negligible, so it should be safe for a driver to give up whenever one of these errors occurs. Although the yurex driver handles -EILSEQ errors in this way, it doesn't do the same for -EPROTO (as discovered by the syzbot fuzzer) or other unrecognized errors. This patch adjusts the driver so that it doesn't log an error message for -EPROTO or -ETIME, and it doesn't retry after any errors.

The driver was clearing its struct usb_device pointer, which it used as an inverted disconnected flag, before deregistering the character device and without serialising against racing release(). This could lead to a use-after-free if a racing release() callback observes the cleared pointer and frees the driver data before disconnect() is finished with it. This could also lead to NULL-pointer dereferences in a racing open().
