[media] cx231xx: disable I2C errors during i2c_scan
Otherwise, it would produce lots of useless messages like: cx231xx: cx231xx_send_usb_command: failed with status --32 After this patch, I2C scan will produce an useful report: [ 9494.050807] cx231xx: i2c_scan: checking for I2C devices on port=0 .. [ 9494.074928] cx231xx: i2c scan: Completed Checking for I2C devices on port=0. [ 9494.074936] cx231xx: i2c_scan: checking for I2C devices on port=3 ..
