This is just a small part of the code, you need to add in all the
other parts from the patch.
Exactly the same addresses would be scanned under each scheme. .My
question is, does the driver need two entry points (detect and probe)
or could only one (probe) be used? I think detect and probe can be the
same function.
With the detect() function it would look somthing like this:
for (address = start; address <= stop;) {
for (; address <=stop; address++) {
do a generic detect
if (driver->detect(address) {
make a new client
client->address = address;
res = device_register(&client->dev);
if (!res)
delete the extra client
}
}
}
