From b263b473bf62dfd4aa10fc9068b2c78b1b20f202 Mon Sep 17 00:00:00 2001 From: Keerthy Date: Thu, 9 Mar 2017 13:36:02 +0530 Subject: [PATCH] thermal: ti-soc-thermal: Remove redundant code ti_thermal_expose_sensor always takes the devm_thermal_zone_of_sensor_register call for registration with the device tree nodes present for all the bandgap sensors for omap3/4/5 and dra7 family. There are large chunks of unused code. Removing all of them.
