[igt-dev] [PATCH i-g-t] [RFC] tests/kms_flip.c: Fix subtests flip-vs-suspend

[Srinivas, Vidya]

Thank you so much Mark. This patch is not required. I have abandoned it.
We needed to stop tlsdate daemon which was holding the RTC lock (initctl stop tlsdated).

Apologies for the same.

Regards
Vidya

Tested it on ChromeOS and it runs well. But I think we should fix the root cause instead.
