[PATCH 4/8] mfd: ti_am335x_tscadc: Unify variable naming when refrencing ti_tscadc_dev

Andrew F. Davis
2016-05-31T17:01:13Z

All functions in this driver reference the same ti_tscadc_dev per device
but use several different names for this structure pointer, this can
be confusing when following the code. Use the name 'tscadc' everywhere.
