    Linus says it is too dangerous to use writes for probing, so we
    stick with pure reads for a while. Hope that 8 possible ranges,
-   check_region, 15 bits of one port and 6 of another make things
+   request_region, 15 bits of one port and 6 of another make things
    likely enough to accept the region on the first hit...
