During driver probe, i2c_imx_init_recovery_info() must come before i2c_add_numbered_adapter(), because the get/set_scl() functions are assigned in i2c_register_adapter() under the conditon that bus recover_info are initialized. Otherwise, get/set_scl() function pointers never get assigned. In such case, when i2c_generic_gpio_recovery() is used for bus recovery, there will be kernel crash because bri->set_scl is NULL. The solution to this bug is moving i2c_imx_init_recovery_info() before i2c_register_adapter().
