Due to some recent optimization done in the way the mac address
bytes are written into the OTP memory, some AR9485 chipsets were
forced to use the first byte from the eeprom template and the
remaining bytes are read from OTP.

AR9485 happens to use generic eeprom template which has 0x1 as
the first byte causes issues in bringing up the card.

So fixed the eeprom template accordingly to address the issue.

When hibernating ->resume may not be called by usb core, but disconnect
and probe instead, so we do not increase the counter after decreasing
it in ->supend. As a result we free memory early, and get crash when
unplugging usb dongle.

Commit fada4ac3 introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by cmtp_del_connection()
which is waiting for the thread to exit -- deadlock.

Removed superfluous event handling which was used to signal
that the rfcomm kthread had been woken. This appears to have been
used to prevent lost wakeups. Correctly ordering when the task
state is set to TASK_INTERRUPTIBLE is sufficient to prevent lost wakeups.

To prevent wakeups which occurred prior to initially setting
TASK_INTERRUPTIBLE from being lost, the main work of the thread loop -
rfcomm_process_sessions() - is performed prior to sleeping.

Disabling the bluetooth usb device embedded in (some) ThinkPads tends to
lead to errors like these:
    btusb_bulk_complete: hci0 urb ffff88011b9bfd68 failed to resubmit (19)
    btusb_intr_complete: hci0 urb ffff88011b46a318 failed to resubmit (19)
    btusb_bulk_complete: hci0 urb ffff88011b46a000 failed to resubmit (19)

That is because usb_disconnect() doesn't "quiesces" pending urbs.

Disconnecting a device is a normal thing to happen so it's no big deal
that usb_submit_urb() returns -ENODEV. The simplest way to get rid of
these errors is to stop treating that return as an error. Trivial,
actually.

While we're at it, add comments to be explicit about the reasons we're
not complaining about -EPERM and -ENODEV.

This cleans up error handling for the beacon in case of dma mapping
failure.  We need to free the skb when dma mapping fails instead of
nulling and leaking the pointer, and we should bail out to avoid
giving the hardware the bad descriptor.

Finally, we need to perform the null check after trying to update
the beacon, or else beacons will never be sent after a single
mapping failure.
