Subject: [PATCH net-next] ath11k: use GFP_ATOMIC under spin lock
Date: Mon, 27 Apr 2020 09:24:17 +0000 [thread overview]
Message-ID: <20200427092417.56236-1-weiyongjun1@huawei.com> (raw)
A spin lock is taken here so we should use GFP_ATOMIC.
Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
