From: Elina Pasheva <epasheva@xxxxxxxxxxxxxxxxxx>
- 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
