Subject: [PATCH 8/8] staging:iio:ad9951: Use spi_sync_transfer()
Date: Sat, 5 Oct 2013 09:45:08 +0200 [thread overview]
Message-ID: <1380959108-21775-8-git-send-email-lars@metafoo.de> (raw)
In-Reply-To: <1380959108-21775-1-git-send-email-lars@metafoo.de>
Use the spi_sync_transfer() helper function instead of open-coding it. Makes the
code a bit shorter.
Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
