    M clang/test/Sema/attr-callback-broken.c

  Log Message:
  -----------
  Improve diagnostic wording for invalid callback attribute uses (#134423)

We were previously telling the user how many arguments were passed to
the attribute rather than saying how many arguments were expected to be
passed to the callback function. This rewords the diagnostic to
hopefully be a bit more clear.

Fixes #47451
