Subject: [PATCH AUTOSEL 4.19 4/8] ieee802154: cc2520: add rc code in cc2520_tx()
Date: Sat, 10 Sep 2022 17:19:17 -0400	[thread overview]
Message-ID: <20220910211921.70891-4-sashal@kernel.org> (raw)
In-Reply-To: <20220910211921.70891-1-sashal@kernel.org>

From: Li Qiong <liqiong@nfschina.com>

[ Upstream commit ffd7bdddaab193c38416fd5dd416d065517d266e ]

The rc code is 0 at the error path "status & CC2520_STATUS_TX_UNDERFLOW".
