Hello,
Included is a patch which corrects the following in driver/spi/spi.c in
function spi_busnum_to_master:
* must allow bus_num 0, the if is really not needed.
* correct the name buffer which is too small for bus_num >= 10000. It
should be 9 bytes big, not 8.
Sorry if I should have split the patch in two.
I am not on the linux-kernel list.
