cdc-acm: fix uninitialized variable
variable struct usb_cdc_parsed_header h may be used
uninitialized in acm_probe.
In kernel 4.8.
/* handle quirks deadly to normal probing*/
if (quirks == NO_UNION_NORMAL)
...
goto skip_normal_probe;
}
we bypass call to
cdc_parse_cdc_header(&h, intf, buffer, buflen);
but later use h in
if (h.usb_cdc_country_functional_desc) { /* export the country data */
