Subject[PATCH 3.16 229/305] ALSA: sparc: Fix invalid snd_free_pages() at error path
3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit 9a20332ab373b1f8f947e0a9c923652b32dab031 upstream.

Some spurious calls of snd_free_pages() have been overlooked and
remain in the error paths of sparc cs4231 driver code. Since
runtime->dma_area is managed by the PCM core helper, we shouldn't
release manually.

Drop the superfluous calls.
