Subject: [PATCH 3.13 082/140] ASoC: tlv320aic32x4: Fix regmap range_min

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

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

From: Markus Pargmann <mpa@...gutronix.de>

commit e8e08c521dc101cf7e7e1caf4f487f9fe11a9a7a upstream.

range_min is the lowest address in the virtual register range. This is
the first register with address 0, not the first register of page 1.

Currently all writes to page 1 are mapped to page 0, so the codec fails
to operate.

Fixes: 4d208ca429ad (ASoC: tlv320aic32x4: Convert to direct regmap API usage)
