[PATCH v2 03/15] staging: iio: isl29028: combine isl29028_proxim_get() and isl29028_read_proxim()

From: Brian Masney
Date: Tue Jan 17 2017 - 04:26:25 EST


isl29028_proxim_get() checks to see if the promixity needs to be
enabled on the chip and then calls isl29028_read_proxim(). There
are no other callers of isl29028_read_proxim(). The naming between
these two functions can be confusing so this patch combines the
two to avoid the confusion.
