3.16.63-rc1 review patch. If anyone has any objections, please let me know.

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.
