Subject: [PATCH net-next 03/13] net: stmmac: Do not return error code in TC Initialization
Date: Mon, 2 Sep 2019 10:01:45 +0200 [thread overview]
Message-ID: <04b637681f523e26fdc61c31e72d1a90d2b3a2b6.1567410970.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
As we can still use the remaining TC callbacks, e.g. CBS. We should not
fail in the initialization only because RX Parser is not available.
