From 2c4ce5041cd5d66875137a854b5e19672dce19a5 Mon Sep 17 00:00:00 2001 From: Cai Huoqing Date: Thu, 21 Oct 2021 20:42:54 +0800 Subject: [PATCH] iio: adc: ina2xx: Avoid double reference counting from get_task_struct/put_task_struct() kthread_run() and kthread_stop() already do reference counting of the task, so remove get_task_struct/put_task_struct() to avoid double reference counting.
