From f94a5becabf43e17490aded8bddc5f924b00338b Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Tue, 23 Mar 2021 15:57:08 +0200 Subject: extconn: Clean-up few drivers by using managed work init Few drivers implement remove call-back only for ensuring a delayed work gets cancelled prior driver removal. Clean-up these by switching to use devm_delayed_work_autocancel() instead. Additionally, this helps avoiding mixing devm and manual resource management and cleans up a (theoretical?) bug from extconn-palmas.c and extcon-qcom-spmi-misc.c where (devm managed)IRQ might schedule new work item after wq was cleaned at remove(). This change is compile-tested only. All testing is appreciated.
