A couple of months ago I thought about this and could think of two
possible solutions:
o add a __moddevtable which expands to __devinitdata
__attribute((unused)).
Drawback: Needs changing of all drivers which produce the warning.
o add a variable which references the table within MODULE_DEVICE_TABLE.
I implemented this, minor drawback is that it costs 4 bytes per table.
However, IIRC Keith didn't like it at this time.
The best option, of course, is to move drivers to the new-style pci or
whatever interface, such that the table actually gets used. But the
middle of a stable series is not necessarily the best time to do so.
