[PATCH 18/20] staging/wilc1000: split out bus specific modules

From: Arnd Bergmann
Date: Tue Nov 10 2015 - 18:46:33 EST


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.
