GCC 7 is not as good as GCC 8+ in telling what is a compile-time const,
and thus could be used for static storage. So we could not use variables
for that, no matter how much "const" keyword is sprinkled around.

I would really like to bump min gcc to 8.5 (RH 8 family),
instead of supporting old Ubuntu. However SLES 15 is also stuck with gcc 7.5 :(

Hi Prezemek,
I ran into a similar problem not so long ago and I'm wondering if
the following, based on a suggestion by Jiri Slaby, resolves your
problem.
diff --git a/drivers/net/ethernet/intel/ice/devlink/health.c

Indeed, no reason to create an (unused) pointer.
And no, don't use macros for strings.
thanks,
