Hi Oliver,
If no further comments we will issue a patch for sierra driver with
sierra_reset_resume() function.
Currently we are waiting for Greg Kroah-Hartman to apply our patch
[PATCH 001/001] USB: serial: sierra driver indat_callback fix
so that we sync with linux-next for the new patch.
Regards,
Elina
