From: Xiao Jiang <[email protected]> The following changes are ensure at24 driver can be probed successfully, which are based on Linux 2.6.36-rc5. 1. Add class, detect and address_list member in at24_driver because they will be check in i2c_detect(). 2. Since the at24 driver are tightly coupled with i2c bus driver, make sure it's init priority is lower than i2c bus.
