Unused `nowayout` module parameter in imx7ulp_wdt

[joggee-fr]

Hi,

I was looking at imx7ulp_wdt watchdog driver (for i.MX93) on branch 6.6-2.2.x-imx and it seems a nowayout module parameter is declared but never used in code. It does not seem to be used on branch 6.12.x+fslc neither.

This is a typical watchdog driver module parameter and some implementation simply call watchdog_set_nowayout() in probe() just like the omap_wdt.

Am I missing something or the flag is really not handled in imx7ulp_wdt?

Hi @joggee-fr

I just wanted to let you know that your analysis is correct.

Please submit a patch upstream that adds watchdog_set_nowayout() in probe().

Thanks @fabioestevam for the confirmation.
TBH, I will not have time right now to submit a patch upstream for this.
So I understand the process is merge upstream then backports here. Am I right?

Hi @joggee-fr

Yes, your understanding is correct.
