I'm on whatever is in F22. gcc -v says

   gcc version 5.1.1 20150618 (Red Hat 5.1.1-4) (GCC)

and the warning looks like so:

  net/mac80211/rate.c: In function =E2=80=98rate_control_cap_mask=E2=80=
=99:
  net/mac80211/rate.c:719:25: warning: =E2=80=98sizeof=E2=80=99 on arra=
y function
parameter =E2=80=98mcs_mask=E2=80=99 will return size of =E2=80=98u8 * =
{aka unsigned char *}=E2=80=99
[-Wsizeof-array-argument]
     for (i =3D 0; i < sizeof(mcs_mask); i++)
                           ^

(note the lack of warning about the use of an array in the function
definition parameter list - I tried to find if there's any way to
enable such a warning, but couldn't find anything. Maybe my google-fu
is weak, but more probably that just doesn't exist).
