Subject: [PATCH] watchdog: hpwdt: Module paramerter alias.
Git-commit: 397a35d418a20453952d707d4b97bae6ac3053ca
Patch-mainline: v4.20-rc1
References: FATE#325978,bsc#1105831

Add module parameter "timeout" as an alias to "soft_margin."
This aligns hpwdt usage more closely with other WDT while
retaining backwards compatibility.
