Since we changed the behaviour of the set_timeout operation in the
watchdog API, we need to change the allready converted drivers so
that they update the timeout field at the end of the set_timeout
operation.

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

Use the current logging styles.
Make sure all output has a prefix.
Add missing newlines.
Remove now unnecessary PFX, NAME, and miscellaneous other #defines.
Coalesce formats.

While receiving WDIOS_DISABLECARD option for WDIOC_SETOPTIONS command,
call wm8350_wdt_stop() to disable watchdog.
Call wm8350_wdt_start() while receiving WDIOS_ENABLECARD option.
Current code has reverse behavior.

At the point of the call to dev_err, wm8350 is NULL.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@
if ((E == NULL && ...) || ...)
{
... when != if (...) S1 else S2
when != E = E1
* E->f
... when any
return ...;
}
else S3
// </smpl>

make the watchdog_info struct const where possible.

The probe and remove functions were incorrectly annotated, with the
misannotation of the remove function causing build failures when built
in.

This driver implements support for the watchdog functionality provided
by the Wolfson Microelectronics WM8350, a multi-function audio and
power management subsystem intended for use in embedded systems. It is
based on a driver originally written by Graeme Gregory, though it has
been extensively modified since then.
Use of a GPIO to kick the watchdog is not yet supported.
