Subject: iio:adis16080: Use spi_sync_transfer()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=af3d5cad0a6699afcae84b578838e698f56028bb;p=deliverable%2Flinux.git

iio:adis16080: Use spi_sync_transfer()

Use the spi_sync_transfer() helper function instead of open-coding it. Makes
the code a bit shorter.
