+Subject: ASoC: ops: Correct bounds check for second channel on SX controls
+
+From: Charles Keepax <ckeepax@opensource.cirrus.com>
+
+commit f33bcc506050f89433a52a3052054d4ebd37b1c1 upstream.
+
+Currently the check against the max value for the control is being
+applied after the value has had the minimum applied and been masked. But
+the max value simply indicates the number of volume levels on an SX
+control, and as such should just be applied on the raw value.
+
+Fixes: 97eea946b939 ("ASoC: ops: Check bounds for second channel in snd_soc_put_volsw_sx()")
