Don't populate the array probe_order on the stack but instead make it
static. Makes the object code smaller by 94 bytes.
Before:
text data bss dec hex filename
41473 13448 320 55241 d7c9 drivers/hwmon/abituguru.o
After:
text data bss dec hex filename
41315 13512 320 55147 d76b drivers/hwmon/abituguru.o
(gcc version 9.2.1, amd64)
