Use the Fixes tag for this.  The format is:

Fixes: ce8a3a9e76d0 ("staging: android: ashmem: Fix a race condition in pin ioctls")

Then you only need one stable CC line.  Just the oldest kernel which
needs to be patched.

Cc: <stable@...r.kernel.org> # 3.18.x

The extra git hash after the stable CC is for if a bug requires several
patches to fix it.  In this case it only requires just this patch so
there's no need to have the hash.

Basically you did extra work which isn't required.  Anyway, this fix was
already merged so no need to resend or anything.
