From a2fa3debc12e4a401a4c6febc1804036a62f1e31 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 9 May 2021 12:33:28 +0100 Subject: [PATCH] iio: light: isl29028: Balance runtime pm + use pm_runtime_resume_and_get() In remove this driver called pm_runtime_put_noidle() but there is no matching get operation. This does not cause any problems because the reference counter will not change if already zero, but it does make the code harder to reason about so should be dropped. Whilst we are here, use pm_runtime_resume_and_get() to replace open coded version.
