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

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.

In commit 86e09287, to reduce memory
usage, the functions of the ath3k module were rewritten to release the
firmware blob after it has been loaded (successfully or not).

The resuting code has some redundancy and the compiler can potentially
produce better code if we omit a function call that is unconditionally
executed in

,----
|     if (ath3k_load_firmware(udev, firmware)) {
|             release_firmware(firmware);
|             return -EIO;
|     }
|     release_firmware(firmware);
|
|     return 0;
| }
`----

It may also be argued that the rewritten code becomes easier to read,
and also to see the code coverage of the snippet in question.
