Subject: [PATCH v3 6/7] spi: s3c64xx: restore removed comments
Date: Tue, 12 Jul 2016 19:02:15 +0900	[thread overview]
Message-ID: <1468317736-18841-7-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1468317736-18841-1-git-send-email-andi.shyti@samsung.com>

Patch a9e93e8 has erroneously removed some comments which are
important to understand why the bus frequency is multiplied by
two during the spi transfer.

Reword the previous comment to a more appropriate message.
