This driver is an AC97 codec according to its help text.  However, if SOUND is
disabled, the "select SND_AC97_BUS" still inserts that into the .config file:

#
# Sound
#
# CONFIG_SOUND is not set
CONFIG_SND_AC97_BUS=m

Even if the config software followed dependency chains on selects, we should
try to limit usage of "select" to library-type code that is needed (e.g., CRC
functions) instead of bus-type support.

Clean up several code points in which the return code from misc_register is
not handled properly.

Several modules failed to deregister various hooks when misc_register fails,
and this patch cleans them up.  Also there are a few modules that legitimately
don't care about the failure status of misc register.  These drivers however
unilaterally call misc_deregister on module unload.

Since misc_register doesn't initialize the list_head in the init_routine if it
fails, the deregister operation is at risk for oopsing when list_del is
called.  The initial solution was to manually init the list in the miscdev
structure in each of those modules, but the consensus in this thread was to
consolodate and do that universally inside misc_register.

The keyboard is connected via GPIOs to the processor, and scanned
using a column sample register. The hardware provides no debouncing
mechanism, so the state of the keys is read KBDSCAN_STABLE_COUNT
times before being reported to the input layer.

The status of the keys needs to be polled because there is no
interrupt hooked to the lines. A workqueue is used for this.

Pass the work_struct pointer to the work function rather than context data.
The work function can use container_of() to work out the data.

For the cases where the container of the work_struct may go away the moment the
pending bit is cleared, it is made possible to defer the release of the
structure by deferring the clearing of the pending bit.

To make this work, an extra flag is introduced into the management side of the
work_struct.  This governs auto-release of the structure upon execution.

Ordinarily, the work queue executor would release the work_struct for further
scheduling or deallocation by clearing the pending bit prior to jumping to the
work function.  This means that, unless the driver makes some guarantee itself
that the work_struct won't go away, the work function may not access anything
else in the work_struct or its container lest they be deallocated..  This is a
problem if the auxiliary data is taken away (as done by the last patch).

However, if the pending bit is *not* cleared before jumping to the work
function, then the work function *may* access the work_struct and its container
with no problems.  But then the work function must itself release the
work_struct by calling work_release().

In most cases, automatic release is fine, so this is the default.  Special
initiators exist for the non-auto-release case (ending in _NAR).
