commit fb9ad24485087e0f00d84bee7a5914640b2b9024 upstream.
Volume can have ranges that start with negative values, ex: -84dB to
+40dB. Apply correct range check in snd_soc_limit_volume before setting
the platform_max. Without this patch, for example setting a 0dB limit on
a volume range of -84dB to +40dB would fail.
