Subject: Bluetooth: Remove redundant setting to zero of bt_cb
X-Git-Tag: android-x86-7.1-r1~1864^2~588^2~42

Bluetooth: Remove redundant setting to zero of bt_cb

The socket allocation functions will always memset skb->cb to zero so
there's no need to make other initializations needing the same thing.
