From 93cacfd41f82eea00b420d62e29a493ca3d07b74 Mon Sep 17 00:00:00 2001 From: Joshua Scott Date: Fri, 9 Sep 2016 17:19:26 +1200 Subject: hwmon: (adt7470) Allow faster removal adt7470_remove will wait for the update thread to complete before returning. This had a worst-case time of up to the user-configurable auto_update_interval. Replace msleep_interruptible with set_current_state and schedule_timeout so that kthread_stop will interrupt the sleep.
