This still doesn't apply against mainline, applying to v3.7 gives:

$ git am -3 --signoff /tmp/fnord
Applying: ASoC: pcm: allow backend hardware to be freed in pause state

Did you hand edit your patch?
It does not apply to blobs recorded in its index.
Cannot fall back to three-way merge.
Patch failed at 0001 ASoC: pcm: allow backend hardware to be freed in pause state

I can't see what's wrong but that's making me worry about applying it
by hand as it seems likely that there's some aspect of it thatd' be
missed; the plain patch program also has similar issues.
