Subject: Bluetooth: Remove pointless parameter check in vhci_send_frame()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=602987758b0a3bfb0af5b0931c302b8f552c8d2e;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Remove pointless parameter check in vhci_send_frame()

The hdev parameter of vhci_send_frame() is always valid. If it were
not valid, then it would have crashed earlier in the call chain.
