+Subject: [PATCH] [PATCH] spi: correct bus_num and buffer bug in spi core
+
+Correct 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.
