staging: line6: clean up line6_variax_process_message()

Previous versions of the line6 driver snooped MIDI traffic in order to
make device state accessible via sysfs attributes. This involved a lot
of logic in line6_variax_process_message() that has since been removed.

Drop unused conditionals in line6_variax_process_message().

staging: line6: drop CONFIG_LINE6_USB_DUMP_PCM

The CONFIG_LINE6_USB_DUMP_PCM config option prints a hexdump of PCM
audio data as URBs are sent and received. The usbmon feature should be
used instead of manually dumping PCM URBs. There are a few advantages
to using usbmon:

* Can be turned on/off at runtime
* Provides full USB-level traffic
* tcpdump and wireshark support for powerful analysis
* No driver-specific code is required

This is the last user of line6_write_hexdump() so we drop it too.

staging: zcache: rename ramster to zcache

[V2: no code changes, patchset now generated via git format-patch -M]

In staging, rename ramster to zcache

The original zcache in staging was a "demo" version, and this new zcache
is a significant rewrite.  While certain disagreements were being resolved,
both "old zcache" and "new zcache" needed to reside in the staging tree
simultaneously.  In order to minimize code change and churn, the newer
version of zcache was temporarily merged into the "ramster" staging driver
which, prior to that, had at one time heavily leveraged the older version
of zcache.  So, recently, "new zcache" resided in the ramster directory.

Got that? No? Sorry, temporary political compromises are rarely pretty.

The older version of zcache is no longer being maintained and has now
been removed from the staging tree.  So now the newer version of zcache
can rightfully reclaim sole possession of the name "zcache".

FYI, this [PATCH 2/5] is simply a "git mv" generated by "git format-patch -M".

staging: comedi: addi_apci_16xx: cleanup addi_find_boardinfo()

This function was originally in the addi-data "common" code and
required using pointer math to access the boardinfo data using

local to this driver we can access the boardinfo directly and

staging: comedi: addi_apci_16xx: cleanup subdevice initialization

The comedi subdevice in this driver is a simple digital i/o

Currently, the code abuses the comedi API by redefining the
COMEDI_SUBD_SERIAL type as COMEDI_SUBD_TTLIO and using that
for the 's->type'. Remove the defines and use the proper type,
COMEDI_SUBD_DIO.

The current code also sets the subdev_flags SDF_GROUND and SDF_COMMON
for the subdevice. These flags really only have meaning for analog
subdevices. Remove them.

All the boards supported by this driver use the same functions for
the subdevice 'insn_*' operations. Remove this information from
the boardinfo and set the s->insn_* operations directly in the init.

staging: comedi: introduce addi_watchdog driver

Many of the ADDI-DATA drivers have a "watchdog" subdevice that can
be used to monitor digital output activity. All the digital outputs
are released (set to 0) if the digital outputs are not accessed, or
the watchdog it not pinged, before the timeout of the watchdog
occurs. The only difference in the drivers for the watchdog subdevice
is the base address used to talk to the watchdog registers.

Instead of duplicating the code needed to support this watchdog,
introduce a helper module, similar to the 8255 module. This module
will be select'ed by the drivers that can use it.

This patch introduces a new macro 'module_comedi_pcmcia_driver'
for comedi PCMCIA drivers which do not do anything special in module
init/exit. This eliminates a lot of boilerplate.

staging: comedi: comedi_buf: factor out common comedi_buf_write_alloc_* code

The only difference between comedi_buf_write_alloc() and the *_strict()
version is that the *_strict() one will only allocate the chunk if it
can completely fulfill the request.

Factor out the common code and add a flag parameter to indicate the 'strict'
usage. Change the exported functions so they are just wrappers around the
common function.

Cleanup the common function a bit and use the comedi_buf_write_n_available()
helper to determine the number of bytes available.

comedi_buf_write_n_available() is not used outside this module so make it
static. Since the only caller is __comedi_buf_write_alloc(), which will
always have a valid async pointer and already has a memory barrier, we
can remove the unnecessary (async == NULL) test as well as the smp_mb().
Also, the rounding of the sample size can be removed since the caller
does not need it.

Setting `info = comedi_file_info_from_minor(minor)` and `dev =
comedi_dev_from_minor(minor)` in the same function is a bit of a waste.
The latter function is just a call of the former followed by a
conditional return of an embedded pointer (`info->device`) or NULL. The
former function uses a spin-lock which is where the wastfulness comes
in.

Move the "followed by a conditional return of an embedded pointer" part
into a new function `comedi_dev_from_file_info` and call this instead of
`comedi_dev_from_minor()` in the places where
`comedi_file_info_from_minor()` is also called.
