Subject: [PATCH v2 0/2] watchdog: s3c2410_wdt: Simplify using dev_err_probe()

Hello,

changes since (implicit) v1, sent with Message-Id:
20230306090919.2206871-1-u.kleine-koenig@...gutronix.de:

 - Rework patch #1 to keep s3c2410_get_wdt_drv_data() as a separate
   function. The return value has to change however to make effective
   use of dev_err_probe(). (I thought about using

   	return ERR_PTR(dev_err_probe(...));

   but this looks too ugly and that's less effective because then
   dev_err_probe cannot be compiled into a tail call.)

 - Squash patches #2 and #3. This destroys the pretty bloatometer
   statistic, in fact bloatometer diagnoses that the code gets bigger.
   I'm a bit surprised but didn't try to understand it. I assume that's
   because the additional parameter that dev_err_probe has to get over
   dev_err is the culprit. Still given that the error code is now
   included in the error message this is an IMHO nice patch.

Now that Gunter likes patch #1 better than the one from v1, I wonder
about his position about patch #2.

Best regards
Uwe
