[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wang ShaoBo <bobo.shaobowang@xxxxxxxxxx>

[ Upstream commit 747da1308bdd5021409974f9180f0d8ece53d142 ]

hci_get_route() takes reference, we should use hci_dev_put() to release
it when not need anymore.

Fixes: 6b8d4a6a0314 ("Bluetooth: 6LoWPAN: Use connected oriented channel instead of fixed one")
