wl1251: split spi interface into separate module
This creates a module called wl1251_spi.ko which contains just the SPI-specific code. The core remains in the module wl1251.ko. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
