Use the BIT macro instead of "open coding" bit fields. This makes it easier to actually see that the bits are not conflicting/overlapping. Signed-off-by:Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This full-speed USB device generates spurious remote wakeup event as soon as USB_DEVICE_REMOTE_WAKEUP feature is set. As the result, Linux can't enter system suspend and S0ix power saving modes once this keyboard is used. This patch tries to introduce USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk. With this quirk set, wakeup capability will be ignored during device configure. This patch could be back-ported to kernels as old as 2.6.39. Signed-off-by:

The current comment sounds like you have to disable some of the ports to be able to use self-powered mode. This is misleading, so change the wording to reflect this. Signed-off-by:

If three or more wireless devices are connected and two of them disconnect between 1-3 seconds apart, it can cause the HWA to disconnect the remaining devices due to failing to see a DN_Alive message from them. This happens because when the HWA detects that the first device is gone, it will attempt to rekey the remaining devices. If one of the devices is not responding because it has also been disconnected but not yet timed out, the synchronous rekey operation running on the wusbd workqueue can block for up to 5 seconds. This will prevent the KEEPALIVE timer from running and DN_Alive messages from being processed because they are processed by the same workqueue. This patch moves the rekey operation to a separate workqueue since it is the only wusb work item that needs to communicate directly with wireless devices. The rest of the WUSB work items either perform no device IO or communicate directly with the host controller and should not be blocked out by a non-responding wireless device. Signed-off-by:

When completing an aborted transfer, skip done segs before calling wa_complete_remaining_xfer_segs to avoid a runtime warning. The warning is harmless in this case but avoiding it prevents false error reports. Signed-off-by:

The existing UWB documentation states that UWB devices show up in /sys/class/uwb and /sys/bus/uwb/devices. Up until the most recent changes to add uwb devices to their own bus, neither of these statements were actually true. Now, UWB devices do show up in /sys/bus/uwb/devices so the documentation has been updated to reflect that and removed references to /sys/class/uwb. The existing documentation also states that local UWB radio controller (RC) devices also show up as UWB devices along with their wireless peer UWB devices under /sys/class/uwb. This is not true so that statement has been removed. Signed-off-by:

Documentation/usb/WUSB-Design-overview.txt states that UWB devices seen by a UWB radio controller are added to /sys/bus/uwb/devices, but this was not actually being done. This functionality is needed in order for UWB peer devices to be enumerated by user mode tools. This patch creates a uwb bus type and adds UWB peer devices to it as they are discovered by the radio controller. Signed-off-by:

Now that we have completely moved from older USB-PHY drivers to newer GENERIC-PHY drivers for PHYs available with USB controllers on Exynos series of SoCs, we can remove the support for the same in our host drivers too. We also defer the probe for our host in case we end up getting EPROBE_DEFER error when getting PHYs. Signed-off-by:

Lately (with the use of uas / bulk-streams) we have been seeing several cases where this error triggers (which should never happen). Add some extra logging to make debugging these errors easier. Signed-off-by:

Even though a Set TR deq ptr command operates on a ring, and an endpoint can have multiple rings, we can have only one Set TR deq ptr command pending. When an endpoint with streams halts or is stopped to unlink urbs, there will only be at most one ring active / one td being executed (the td stopped_td points to). So when we reset the endpoint (for a halt), or the stop command completes, we will queue one Set TR deq ptr command at most, cancelled urbs on other stream rings then the one being executed will have there trbs turned to nops, and once the hcd gets around to execute that stream ring they will be simply skipped. So the SET_DEQ_PENDING flag in the endpoint is sufficient protection against starting the endpoing before all stream rings are cleaned up. Signed-off-by:

Even if the stream for which the command was intended has been freed in the mean time. This ensures that things start rolling again after an unlink / halt. Signed-off-by:

xhci_queue_new_dequeue_state is the only caller of queue_set_tr_deq and queue_set_tr_deq checks for SET_DEQ_PENDING, where as xhci_queue_new_dequeue_state sets it which is inconsistent. Simply fold the 2 into one is a nice cleanup and fixes the inconsistency. Signed-off-by:

V2 - Restart polling (which will restart the timer) for the shared HCD in xhci_resume(). xhci_suspend() will stop the primary HCD's root hub timer, but leaves the shared HCD's timer running. This change adds stopping of the shared HCD timer. Signed-off-by:

There are multiple reasons for this: 1) This fixes a missing check for xhci_alloc_command failing in xhci_handle_cmd_stop_ep() 2) This adds a warning when we cannot set the new dequeue state because of xhci_alloc_command failing 3) It puts the allocation of the command after the sanity checks in queue_set_tr_deq(), avoiding leaking the command if those fail 4) Since queue_set_tr_deq now owns the command it can free it if queue_command fails 5) It reduces code duplication Signed-off-by:

If something goes wrong in our communication with an uas device we may get a response iu in reaction to a cmnd, rather then a status iu. In this case propagate an error upwards, rather then logging a bogus iu message. Signed-off-by:

Instead of doing: uas_log_cmd_state(cmnd, __func__) scmd_printk(KERN_ERR, cmnd, "error doing foo %d\n", err) On error, resulting in 2 log calls for a single error, make uas_log_cmd_state take a status code, and change calls like the above to: uas_log_cmd_state(cmnd, "error doing foo", err) Also change various sanity checks (which should never trigger) from: "scmd_printk(KERN_ERR, cmnd, "sanity foo failed\n")" to calling the new uas_log_cmd_state(), so that when they do trigger we get more info.

I've access to a number of different uas devices now, and none of them use old style sense urbs. The only case where these code-paths trigger is with the asm1051 and there they do the wrong thing, as the asm1051 sends 8 bytes status iu-s when it does not have any sense data, but uses new style sense iu-s regardless, as can be seen for scsi cmnds where there is sense data.

It was only used to sanity check against completing the same cmnd twice, but that is the case we're likely operating on free-ed memory, and doing sanity checks on free-ed memory is not really helpful. Signed-off-by:
