Variable "hw_pre_value" is not used anywhere in the

This patch removes this variable.

Jean Delvare 487722cf2d watchdog: Get rid of MODULE_ALIAS_MISCDEV statements
I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

Either the device is enumerated and the driver already has a module
alias (e.g. PCI, USB etc.) that will get the right driver loaded
automatically.

Or the device is not enumerated and loading its driver will lead to
more or less intrusive hardware poking. Such hardware poking should be
limited to a bare minimum, so the user should really decide which
drivers should be tried and in what order. Trying them all in
arbitrary order can't do any good.

On top of that, loading that many drivers at once bloats the kernel
log. Also many drivers will stay loaded afterward, bloating the output
of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
loaded as a dependency) can't even be unloaded!

If defining char-major-10-130 is needed then it should happen in
user-space.

Kuppuswamy Sathyanarayanan 712b6aa873 intel_mid: Renamed *mrst* to *intel_mid*
mrst is used as common name to represent all intel_mid type
soc's. But moorsetwon is just one of the intel_mid soc. So
renamed them to use intel_mid.

This patch mainly renames the variables and related
functions that uses *mrst* prefix with *intel_mid*.

To ensure that there are no functional changes, I have compared
the objdump of related files before and after rename and found
the only difference is symbol and name changes.

Kuppuswamy Sathyanarayanan 05454c26eb intel_mid: Renamed *mrst* to *intel_mid*
Following files contains code that is common to all intel mid
soc's. So renamed them as below.

mrst/mrst.c              -> intel-mid/intel-mid.c
mrst/vrtc.c              -> intel-mid/intel_mid_vrtc.c
mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c
pci/mrst.c               -> pci/intel_mid_pci.c

Also, renamed the corresponding header files and made changes
to the driver files that included these header files.

To ensure that there are no functional changes, I have compared
the objdump of renamed files before and after rename and found
that the only difference is file name change.

Donald Johnson 57539c1cf9 watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms.
This submission includes:
  - Fix to intel_scu_write() to start watchdog timer the on the
    first write, and refresh on subsequent writes.
    This enables Open, write, write, ... usage model.
  - Moves boot parameter checks from intel_scu_open() to
    intel_scu_watchdog_init(), so driver init will fail if these
    parameters are out of bounds.
  - Adds check for whether process waiting in wait_event_interruptible()
    received a signal while it was waiting.
  - Other small error handling changes.

Removed the read() method for now as that wass a non-standard behaviour.
