RE: bluetooth: module_refcount is not decreased when connection times out

Hi Bing,

quoted

The module refcount is increased by hci_dev_hold() call in hci_conn_add=

() in hci_conn.c, and it is

decreased by hci_dev_put() call in "del_conn" (hci_sysfs.c).

In case connection timeout happens, hci_dev_put() is never called.

can you test the attached patch for quickly. It should fix it.

Hi Marcel,

It seems that hdev is "put" twice with the patch, if the connection fails.

# hciconfig hci0 up
# lsmod | grep btusb				-> "used by" refcount =3D 1

# hcitool cc <non-exisiting bdaddr>		-> will get timeout
# lsmod | grep btusb				-> "used by" refcount =3D 0 (??)

# hcitool cc <non-exisiting bdaddr>		-> time out again
# lsmod | grep btusb				-> "used by" refcount =3D 4294967295 (??)


Thanks,

Bing
