[PATCH 17/19] staging/wilc1000: split out bus specific modules

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SPI and SDIO specific code is now separate enough that
we just need to restructure the Makefile and Kconfig logic
a bit and export a couple of symbols from the common module
to have separate bus glue drivers.
