Subject: [PATCH v3] ath10k: high latency fixes for beacon buffer
Date: Wed, 18 Aug 2021 20:26:27 -0300	[thread overview]
Message-ID: <20210818232627.2040121-1-festevam@denx.de> (raw)

From: Alagu Sankar <alagusankar@silex-india.com>

Beacon buffer for high latency devices does not use DMA. other similar
buffer allocation methods in the driver have already been modified for
high latency path. Fix the beacon buffer allocation left out in the
earlier high latency changes.
