spi/tegra20-slink: Remove unused is_single_xfer check
Currently transfer_one_message() checks to see if the message consists of a single spi_transfer and tells _start_transfer_one() but it just ignores this. Don't bother. Signed-off-by: Mark Brown <broonie@linaro.org> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>
