Subject: [PATCH 5.4 10/43] net: ethernet: lpc_eth: Handle error for clk_enable
Date: Mon, 14 Mar 2022 12:53:21 +0100 [thread overview]
Message-ID: <20220314112734.708604987@linuxfoundation.org> (raw)
In-Reply-To: <20220314112734.415677317@linuxfoundation.org>
From: Jiasheng Jiang <jiasheng@iscas.ac.cn>
[ Upstream commit 2169b79258c8be803d2595d6456b1e77129fe154 ]
As the potential failure of the clk_enable(),
it should be better to check it and return error
if fails.
Fixes: b7370112f519 ("lpc32xx: Added ethernet driver")
