Subject: [PATCH v3 4/7] spi: s3c64xx: use error code from clk_prepare_enable()
Date: Tue, 12 Jul 2016 19:02:13 +0900	[thread overview]
Message-ID: <1468317736-18841-5-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1468317736-18841-1-git-send-email-andi.shyti@samsung.com>

If clk_prepare_enable() fails do not return -EBUSY but use the
value provided by the function itself.
