Subject: Bluetooth: Check status of command complete for HCI_Reset
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8761f9d6620b0be6b08f21807568fbbfcbb128d2;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Check status of command complete for HCI_Reset

When the HCI_Reset command returns, the status needs to be checked. It
is unlikely that HCI_Reset actually fails, but when it fails, it is a
bad idea to reset all values since the controller will have not reset
its values in that case.
