spi/spi_nuc900: Use spi_bitbang_stop instead of spi_unregister_master in nuc900_spi_remove
Calling spi_bitbang_stop() will also destroy bitbang->workqueue, which is created by calling spi_bitbang_start() in nuc900_spi_probe(). Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
