From af51ec8c9213ec502c3f5c9f5860dd98fceb3433 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 9 May 2021 12:33:34 +0100 Subject: [PATCH] iio: hid: trigger: Balance runtime pm + use pm_runtime_resume_and_get() The call to pm_runtime_put_noidle() in remove() callback is not balanced by any gets Note this doesn't cause any problems beyond reader confusion as the runtime pm core protects against the reference counter going negative. Whilst here, use pm_runtiem_resume_and_get() to simplify code a little.
