[PATCH 3.12 040/116] ALSA: pcsp: Fix the order of input device unregistration

[Greg Kroah-Hartman]

3.12-stable review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit 6408eac2665955343cd0e4bcd7d6237ce39611ed upstream.

The current code may access to the already freed object.  The input
device must be accessed and unregistered before freeing the top level
sound object.
