I was able to reproduce the issue without this patch.
Applied this patch on next-20250227 kernel and tested the patch and
issue is fixed.

Hi George,
why is armada_37xx_wdt also here?
The stop function in that driver may not sleep.
Marek
A new option flag is added to watchdog_info. This helps the watchdog
core to check whether stop functions would sleep or not.
The option flags of individual drivers are also updated accordingly.
