Merge tag 'kgdb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux

Pull kgdb updates from Daniel Thompson:
 "It has been a quiet dev cycle for kgdb. There has been some good stuff
  for kdb on the mailing list but unfortunately the patches caused a
  couple of problems with the kdb pager so I had to drop those and they
  will have to wait for next time!

  That just leaves us with just a couple of very tiny clean ups for now:

   - Fix a broken comment

   - Use str_has_prefix() for the grep "pipe" in kdb"

* tag 'kgdb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
  kgdb: fix comment regarding static function
  kdb: Replace strncmp with str_has_prefix
