Clearly something is wrong here, but I can't quite figure out what.
Changing the array size to 16 bytes avoids the warning, but is
probably the wrong solution here.
Ugh. drm_dp_channel_eq_ok() does not

It also affects the optimizer in two different ways AFAIK:

the warnings appear again in 8.1/8.2/current 9.0, see [2] below. I
guess that is a result of the warnings requiring some optimization
passes enabled. Martin Sebor (CC'd) fixed some false positives from
what I can see in gcc'

Martin Sebor also asked me about this, he's the one that worked on
the gcc code that introduced the warning. Sorry for not replying earlier.
Maybe you can pass this to him? (maybe open a bug in gcc's bugzilla?)
I've opened bug 84725 to extend attribute nonstring to the othe
functions, I would favor supporting
the warning and the attribute for all the three types.
[By the way, CC'ing Xiongfeng, Willy and Arnd, since they were
involved in the example report; sorry guys!].
