The PDEBUG macro is used to output a bunch of debug messages in the
driver. These messages might be useful when first creating the driver
but they shouldn't be in mainline. Remove it.

The PCL812_EXTDEBUG define enables a bunch of function tracing debug
messages as well as a dump of the comedi_cmd info during the cmdtest.
There are better ways to do the function tracing and the cmdtest
dump shouldn't be in the driver. Just remove all of it.

Currently the amount of pools each client can use is limited to 16, this is
and arbitrary limit which isn't really required by current implementation.
This places and arbitrary limit on the number of mounted filesystems that
can use cleancache.
This patch removes that limit and uses IDR to do sparse mapping of pools
in each client.

Changed setting the status bits to a byte-oriented approach. Number of
written status bits is now based on VHCI_NPORT, instead of casting
status buffer to a long. This fixes a stack corruption bug on 64-bit
based architectures, and potential byte order / endianness related
issues.
In addition updated function comments, and log statements.

This patch fixes an uninitialized variable warning in
alloc_zspage(). It also fixes the secondary issue of
prev_page leaving scope on each loop iteration. The only
reason this ever worked was because prev_page was occupying
the same space on the stack on each iteration.

Refactor the subdev_8255_insn function to follow what the user
space library is doing.
1) This function requires 'data' to contain 2 parameters. Add a
sanity check for this (insn->n != 2).
2) The 'data' parameters are actually a 'mask' of the valid bits and
the actual 'bits' to modify. Create local variables of these names
to help with maintainability.
3) The value returned in data[1] reflects the actual state of the
8255 io pins after the update of the masked bits. Fetch this data
in a local variable and then set data[1].
4) The user space library only checks for a < 0 return to indicate
an error. It appears that the 'return 2' in this function is supposed
to indicate the number of data parameters used to perform the command.
Return the insn->n value for this, the open coded '2' looks wrong.

For TV Devices:
The values taken from XGI_TVDelayList are always overwritten with the
values from XGI_TVDelayList2 since the if condition for using the values
from XGI_TVDelayList2 is identical with the check to enter this scope and
thus always true.
The delay values in XGI_TVDelayList2 is always 0x22 so we
can simply replace it with this constant value.
For LCD Devices:
The LCD_DelayCompensation field is always set to 0x12 so we can simply
replace this field with a constant value.
This saves about 500 bytes in compiled size.

Having automatic updates seems pointless for production system, and
even dangerous and thus counter-productive:
1. If we can mount pstore, or read files, we can as well read
/proc/kmsg. So, there's little point in duplicating the
functionality and present the same information but via another
userland ABI;
2. Expecting the kernel to behave sanely after oops/panic is naive.
It might work, but you'd rather not try it. Screwed up kernel
can do rather bad things, like recursive faults[1]; and pstore
rather provoking bad things to happen. It uses:
1. Timers (assumes sane interrupts state);
2. Workqueues and mutexes (assumes scheduler in a sane state);
3. kzalloc (a working slab allocator);
That's too much for a dead kernel, so the debugging facility
itself might just make debugging harder, which is not what
we want.
Maybe for non-oops message types it would make sense to re-enable
automatic updates, but so far I don't see any use case for this.
Even for tracing, it has its own run-time/normal ABI, so we're
only interested in pstore upon next boot, to retrieve what has
gone wrong with HW or SW.
So, let's disable the updates by default.
