staging: wfx: wfx_init_common() returns NULL on error
Smatch complains: bus_spi.c:228 wfx_spi_probe() warn: 'bus->core' could be an error pointer bus_sdio.c:221 wfx_sdio_probe() warn: 'bus->core' could be an error pointer bus->core contains the result of wfx_init_common(). With this patch, wfx_init_common() returns a valid pointer or NULL.
