Subject: [PATCH AUTOSEL 4.19 146/219] net: stmicro: fix a missing check of clk_prepare
Date: Fri, 22 Nov 2019 00:47:58 -0500	[thread overview]
Message-ID: <20191122054911.1750-139-sashal@kernel.org> (raw)
In-Reply-To: <20191122054911.1750-1-sashal@kernel.org>

From: Kangjie Lu <kjlu@umn•edu>

[ Upstream commit f86a3b83833e7cfe558ca4d70b64ebc48903efec ]

clk_prepare() could fail, so let's check its status, and if it fails,
return its error code upstream.
