Subject: [PATCH] ath11k: qmi: avoid error messages when dma allocation fails
Date: Mon, 23 Aug 2021 14:32:58 +0800 [thread overview]
Message-ID: <20210823063258.37747-1-aaron.ma@canonical.com> (raw)
qmi tries to allocate a large contiguous dma memory at first,
on the AMD Ryzen platform it fails, then retries with small slices.
So set flag GFP_NOWARN to avoid flooding dmesg.
