No. Between summer, holidays and a conference I didn't get to do it.

Done the minimal approach here:

  https://github.com/ojeda/linux/commits/compiler-attributes-backport

Tested building a handful of drivers with gcc 4.6.4, 8.3.0 and 9.1.1.

Greg, I could backport the entire compiler_attributes.h, but given
this is stable, we are supposed to minimize changes, right?

I tried to imitate what you do in other stable patches, please check
the Cc:, Link: lines and the "commit ... upstream" just in case.

HTH,

Cheers,
Miguel
