Subject: Bluetooth: Return ENODATA in hci_req_run
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=382b0c39b3f5b239e3fc07712027fcd4d503bd26;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Return ENODATA in hci_req_run

In case the HCI request queue is empty, hci_req_run should return
ENODATA instead of EINVAL. This way, hci_req_run returns a more
meaningful error value.
