Subject[PATCH 09/19] staging/wilc1000: move init/exit functions to driver files
Date
The driver interfaces are in linux_wlan_sdio.c and linux_wlan_spi.c, so
this is where the init and exit functions should be. Splitting this up
enables further cleanups, including eventually allowing both modules
to be built together.
