[PATCH v2 4/5] mfd: ti_am335x_tscadc: Rename regmap_tscadc to regmap

From: Andrew F. Davis
Date: Wed Jun 08 2016 - 11:56:27 EST

The regmap structure pointer is named regmap_tscadc, this is not
consistent with other drivers and is redundant, it also contributes
to several checkpatch warnings involving long lines. Rename this.
