Since all the asserts and DBC macros are gone, the kconfig macro
CONFIG_TIDSPBRIDGE_DEBUG is not almost used, but for printing trace messages.

Since it is almost not used, I don't see any case for keep it churning the
configuration menu.

This patch removes completely the kconfig macro CONFIG_TIDSPBRIDGE_DEBUG,
using only TIDSPBRIDGE_BACKTRACE for enabling the debug trace messages.

This macro is only valid when CONFIG_TIDSPBRDIGE_DEBUG is enabled and it only
prints a log message, it is not a real assertion mechanism like BUG_ON() or
WARN_ON().

It is better to remove them: less code to maintain.

The kernel does not use a "Design by Contract" approach, and it is only
activated in the module if CONFIG_TIDSPBRDIGE_DEBUG is enabled, so they are

tidspbridge when built as a module is named bridgedriver.

bridgedriver is not a particularly good module name.

tidspbridge is what the source is named.  That seems
a more appropriate module name too as it describes
the hardware function better.

This patch cleans up the coding style in
drivers/staging/vt6656/wpactl.c to closer match the generally accepted
kernel CodingStyle. It is by no means a "make it perfect" patch, but
it does get the file a fair bit closer to matching the accepted style
(whomever was involved in the evolution of this file seriously need to
configure their editors to maintain a consistent style - it was a
mess).

Besides pure style cleanups I also took the liberty of removing some
pointless parens, some unneeded casts and removing some commented out code
(it was obviously not used and git has it if it's ever needed in the
future).

There are several features of the Line6 USB driver which require PCM
data to be exchanged with the device:
*) PCM playback and capture via ALSA
*) software monitoring (for devices without hardware monitoring)
*) optional impulse response measurement
However, from the device's point of view, there is just a single
capture and playback stream, which must be shared between these
subsystems. It is therefore necessary to maintain the state of the
subsystems with respect to PCM usage. We define several constants of
the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
following meanings:
*) <subsystem> is one of
-) ALSA: PCM playback and capture via ALSA
-) MONITOR: software monitoring
-) IMPULSE: optional impulse response measurement
*) <direction> is one of
-) PLAYBACK: audio output (from host to device)
-) CAPTURE: audio input (from device to host)
*) <resource> is one of
-) BUFFER: buffer required by PCM data stream
-) STREAM: actual PCM data stream

The subsystems call line6_pcm_acquire() to acquire the (shared)
resources needed for a particular operation (e.g., allocate the buffer
for ALSA playback or start the capture stream for software monitoring).
When a resource is no longer needed, it is released by calling
line6_pcm_release(). Buffer allocation and stream startup are handled
separately to allow the ALSA kernel driver to perform them at
appropriate places (since the callback which starts a PCM stream is not
allowed to sleep).

I am preparing to convert this driver from semaphore to mutex locking,
The first step has been to eliminate a number of semaphores that were
initialized but never used, and one whose only use was a single "up"
after initialization. A total of 9 semaphores were removed in this process.

One other change was to remove some inline semaphore routines that were
unused.

In addition, several cases had the following structure:

down()
if () {
   ...
}
up()

The locking overhead was reduced by moving the up/down inside the if
block.
