Axel Lin c2572b78aa USB: cdc-acm: fix resource reclaim in error path of acm_probe ... This patch fixes resource reclaim in error path of acm_probe: 1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there is no need to call acm_read_buffers_free(acm) here. Fix it by goto alloc_fail6 instead of alloc_fail7. 2. In the case of "out of memory (write urbs usb_alloc_urb)", usb_alloc_urb may fail in any iteration of the for loop. Current implementation does not properly free allocated snd->urb. Fix it by goto alloc_fail8 instead of alloc_fail7. 3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate) fail, acm->country_codes is kfreed. As a result, device_remove_file for dev_attr_wCountryCodes will not be executed in acm_disconnect. Fix it by calling device_remove_file for dev_attr_wCountryCodes before goto skip_countries.
