[PATCH 10/12] staging: iio: tsl2x7x: make logging consistent and correct newlines

From: Brian Masney
Date: Sat Mar 03 2018 - 20:56:50 EST


This patch updates all of the logging commands so that they are
consistent with the other messages, includes __func__ in the message,
and all of the messages include newlines.

This patch also removes some debug log messages from tsl2x7x_prox_cal().
