SPI controller drivers handle this case fine. r310492: [spigen] Fix spigen attaching as a driver for SPI devices nodes in FDT Return BUS_PROBE_NOWILDCARD in probe method to make sure that spigen attaches only to the device created in identify method. Before this change spigen probe method used to return 0 which meant it competed with other drivers to be attached to the devices created for child nodes of SPI bus node in FDT.
