nowayout is actually a boolean value.
So make it bool for all watchdog device drivers.

This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

This is the same case as fschmd, from which the code was copied as far
as I can see. So the same clean-up applies:

The WDIOC_GETSUPPORT ioctl only needs a mutex because it operates on a
static variable. There is no good reason to keep this variable static,
so let's just make it non-static and drop the now useless mutex
altogether.

We have a standard intrusion detection interface now, drivers should
implement it. I've left the old interface in place for the time being,
with a deprecation warning, it will be removed later.

<title>drivers: autoconvert trivial BKL users to private mutex</title>

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

These drivers do not seem to be under active
maintainance from my brief investigation. Apologies
to those maintainers that I have missed.
