This has never worked properly because wsize passed to cxacru_cm() is incorrectly set to the number of values instead of the data bytes. The maximum number of values that can be set at once is 7 which means the device will not get enough data to work with and none of the configuration values will be used. At least one existing cxacru-cf.bin file contains invalid data which will prevent the modem from syncing properly. Fixing it is likely to break existing systems, and the new sysfs interface for setting configuration parameters can provide the same functionality. A script is provided to convert from the original format. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
