From 29cf142cefede765664f33a394a1b72c1cc5f1f6 Mon Sep 17 00:00:00 2001 From: Song Hongyan Date: Tue, 25 Oct 2016 01:06:03 +0000 Subject: [PATCH] iio: orientation: hid-sensor-rotation: Add PM function (fix non working driver) commit 8af644a7d6846f48d6b72be5d4a3c6eb16bd33c8 upstream. This fix makes newer ISH hubs work. Previous ones worked by lucky coincidence. Rotation sensor function does not work due to miss PM function. Add common hid sensor iio pm function for rotation sensor. Further clarification from Srinivas: If CONFIG_PM is not defined, then this prevents this sensor to function. So above commit caused this. This sensor was supposed to be always on to trigger wake up in prior external hubs. But with the new ISH hub this is not the case.
