Subject[PATCH 3.2 073/149] ASoC: max98095: a couple array underflows
3.2.52-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit f8d7b13e14357ed19d2ca2799539600418dc3939 upstream.

The ->put() function are called from snd_ctl_elem_write() with user
supplied data. The limit checks here could underflow leading to a
crash.
