Subject: [PATCH v4 08/10] mtd: st_spi_fsm: General tidy-up
Date: Wed, 21 Jan 2015 15:24:26 +0000	[thread overview]
Message-ID: <1421853868-8262-9-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1421853868-8262-1-git-send-email-lee.jones@linaro.org>

Due to the nature of the port (lots of copy/paste) much of the white-space
is taken up by spaces instead of tab separators. This patch aims to change
that.
