Are there any documentation on what the changes in the i2c modules are going from 2.6.22 to 2.6.31.
The driver which compiles and runs on 2.6.22 returns the following errors when compiled on 2.6.31.
I have included the correspondign lies from the code to clarify my predicament. Due to the current urgency I am sticking to the old binding method as the new method requires more indepth understanding. Are there ways to get over the following messages?
error: unknown field �detach_client� specified in initializer
device_create(lkmoz_class,NULL,lkomz_dev_number, LKOMZ_DEV_NAME)
=>error: too few arguments to function �device_create�
i2c_probe(adapter,&lkomz_addr_data,lkomz_attach)
=>error: implicit declaration of function �i2c_probe�
i2c_detach_client(client)
=>error: implicit declaration of function �i2c_detach_client�
make[1]: Leaving directory `/usr/src/kernels/linux-2.6.31'
make: *** [all] Error 2
Any help would be greatly appreciaetd.
Thanking you.

Yes.

The best thing for you to do is get it into the main kernel tree, then
it will remain compatible with future kernel versions as the API changes
over time.
