When trying to add DT support to the DA9063 WDT, I didn't want to add yet
another error message when watchdog_init_timeout fails. The core could do this
with more detail, and also much more consistent. So, I refactored this routine
and removed error strings from its callers. Note that DA9063 support is not
added here but was sent seperately[1]. This series has been tested using the
renesas_wdt driver on a Renesas Salvator-XS board (R-Car M3N) and build bot is
happy, too.

A branch (based on Guenter's watchdog-next) for testing can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/wdt-handover

Changes since V2:

* refactored patch 2 to use pr_* instead of dev_* and fall back to wdt
  'identity' if there is no dev attached. Thanks Jerry for the report!
* added rev tag to patch 1 (thanks Guenter for the discussion!)
* added ack tag to patch 5 (thanks William!)

Changes since V1:

* return -EINVAL if DT supplied a value of '0' [patch 1]
* update kdoc to mention that DT cannot be '0' but module_param can be
  [patch 1]
* add Guenter's Rev-by to all patches except patch 1
* add driver maintainers to CC this time

I think we are ready to go now?

Thanks,

   Wolfram
