Pull btrfs fixes from Chris Mason:
"It turns out that we had two crc bugs when running fsx-linux in a
loop. Many thanks to Josef, Miao Xie, and Dave Sterba for nailing it
all down. Miao also has a new OOM fix in this v2 pull as well.
Ilya fixed a regression Liu Bo found in the balance ioctls for pausing
and resuming a running balance across drives.
Josef's orphan truncate patch fixes an obscure corruption we'd see
during xfstests.
Arne's patches address problems with subvolume quotas. If the user
destroys quota groups incorrectly the FS will refuse to mount.
The rest are smaller fixes and plugs for memory leaks."

This patch is to set power.async_suspend for usb port in order
to allow it to be suspended and resumed asynchronously during
system sleep transitions.
The power.async_suspend flag is also set for devices that don't have
suspend or resume callbacks, because otherwise they would make the
main suspend/resume thread wait for their "asynchronous" children
(during suspend) or parents (during resume), effectively negating the
possible gains from executing these devices' suspend and resume
callbacks asynchronously.

This patch is to add usb port auto power off mechanism.
When usb device is suspending, usb core will suspend usb port and
usb port runtime pm callback will clear PORT_POWER feature to
power off port if all conditions were met. These conditions are
remote wakeup disable, pm qos NO_POWER_OFF flag clear and persist
enable. When it resumes, power on port again.
Add did_runtime_put in the struct usb_port to ensure
pm_runtime_get/put(portdev) to be called pairedly. Set did_runtime_put
to true when call pm_runtime_put(portdev) during suspending. The
pm_runtime_get(portdev) only will be called when did_runtime_put
is set to true during resuming. Set did_runtime_put to false after
calling pm_runtime_get(portdev).
Make clear_port_feature() and hdev_to_hub() as global symbol.
Rename clear_port_feature() to usb_clear_port_feature() and
hdev_to_hub() to usb_hub_to_struct_hub().
Extend hub_port_debounce() with the fuction of debouncing to
be connected. Add two wraps: hub_port_debounce_be_connected()
and hub_port_debouce_be_stable().
Increase HUB_DEBOUNCE_TIMEOUT to 2000 because some usb ssds
needs around 1.5 or more to make the hub port status to be
connected steadily after being powered off and powered on.

support to mainline kernel.
The PHY layer now allows us to have mulitple PHYs

There's also a few cleanups here: removal of __dev*

This patch (as1646) fixes a long-standing bug in the USB hub driver.
Upon conversion from char to unsigned long, the bytes in the status
buffer are subject to unwanted sign extension. The bytes should be
declared as u8 rather than char, to prevent this.
This effects of this bug are minimal. The hub driver may end up doing
a little unnecessary extra work because it thinks events have occurred
on some ports when they really haven't.

for function uhci_sprint_schedule:
the buffer len is MAX_OUTPUT: 64 * 1024, which may not be enough:
may loop UHCI_NUMFRAMES times (UHCI_NUMFRAMES is 1024)
each time of loop may get more than 64 bytes
so need check the buffer length to avoid memory overflow
this patch fix it like this:
at first, make enough room for buffering the exceeding contents
judge the contents which written whether bigger than buffer length
if bigger (the exceeding contents will be in the exceeding buffer)
break current work flow, and return.
