USB: serial: sierra driver interrupt urb resubmit fix
- Fixed a problem when re-submitting urb from interrupt callback in function sierra_instat_callback(). This suppresses also issuing of error messages in /var/log/kern.log - Removed redundant debug message at the beginning of sierra_instat_callback() function - Changed a debug message to be an error message Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
