Subject: [PATCH] watchdog: hpwdt: Claim NMIs generated by iLO5
Git-commit: 62290a5c194b30a096cbcc6bb8680a5a1e627714
Patch-mainline: v4.18-rc1
References: FATE#325978,bsc#1105831
On iLO5 going forward we want to return and not claim the NMI, if
the NMI was NOT gnerated by the iLO as a result of the watchdog
timing out or an explicit generate NMI.
The sense of the test in is inverted and prevents hpwdt_pretimeout
from claiming NMIs when it should.
