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

commit cfef67f016e4c00a2f423256fc678a6967a9fc09 upstream.
In snd_hda_parse_generic_codec(), 'spec' is allocated through kzalloc(). Then, the pin widgets in 'codec' are parsed. However, if the parsing process fails, 'spec' is not deallocated, leading to a memory leak.
To fix the above issue, free 'spec' before returning the error.
