ssb_wait_bit was designed for only one-bit bitmasks.
People start using it for multi-bit bitmasks. Make the "set" case
is safe for this. The "unset" case is already safe.

This does not change behavior of the current code.

have a clear separation between the commands related to BR/EDR and
LE. Commands and responses in the LE signaling channel are not being
handled yet, command reject is sent to all received requests. Bluetooth

Commit: "p54: enhance rssi->dBm database import"
changed the way how the driver deals with the
rssical data. A new data format was necessary
and hence this patch.

NOTE: (for users with a custom eeprom binary)
I spent some time updating p54tools to support
the new format too: => (git available from)
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

It now comes with a simplistic script "n800_rssi2v2.sh"
which can be used to automate the conversion.

This patch fixes several shortcomings of the
previous implementation. Features of the
rewrite include:

 * handles undocumented "0x0000" word at the
   start of the frequency table.
   (Affected some early? DELL 1450 USB devices
    and my Symbol 5GHz miniPCI card.)

 * supports more than just one reference point
   per band. (Also needed for the Symbol card.)

 * ships with default values in case the eeprom
   data is damaged, absent or unsupported.

Writing beacon to device happen through multiple write command calls.
zd_usb_iowrite16v uses synchronous urb call and with multiple write
commands in row causes high CPU usage.

This patch makes zd_usb_iowrite16v use asynchronous urb submit within
zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing
multiple commands to device using zd_usb_iowrite16v_async. Each URB
is delayed and submitted to device by next zd_usb_iowrite16v_async
call or by call to zd_usb_iowrite16v_async_end. URBs submitted by
zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB
send by zd_usb_iowrite16v_async_end does not. This lower CPU
usage when doing writes that require multiple URBs.

zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint.
However usb_bulk_msg() internally corrects this and makes interrupt URB.

It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less
confusion.
