Subject: Bluetooth: Make hci_req_add returning void
X-Git-Tag: firefly_0821_release~3680^2~478^2~21^2^2~234^2~32
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e348fe6bbab85c513816d2536ffabac4be016442;p=firefly-linux-kernel-4.4.55.git

Bluetooth: Make hci_req_add returning void

Since no one checks the returning value of hci_req_add and HCI
request errors are now handled in hci_req_run, we can make hci_
req_add returning void.
