Subject: [PATCH] wlcore: fix runtime pm imbalance in wl1271_op_suspend
Date: Wed, 20 May 2020 20:57:22 +0800 [thread overview]
Message-ID: <20200520125724.12832-1-dinghao.liu@zju.edu.cn> (raw)
When wlcore_hw_interrupt_notify() returns an error code,
a pairing runtime PM usage counter decrement is needed to
keep the counter balanced.
