Merge tag 'auto-type-conversion-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-auto

Pull __auto_type to auto conversion from Peter Anvin:
 "Convert '__auto_type' to 'auto', defining a macro for 'auto' unless
  C23+ is in use"

* tag 'auto-type-conversion-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-auto:
  tools/virtio: replace "__auto_type" with "auto"
  selftests/bpf: replace "__auto_type" with "auto"
  arch/x86: replace "__auto_type" with "auto"
  arch/nios2: replace "__auto_type" and adjacent equivalent with "auto"
  fs/proc: replace "__auto_type" with "const auto"
  include/linux: change "__auto_type" to "auto"
  compiler_types.h: add "auto" as a macro for "__auto_type"
