Subject: Bluetooth: Remove pointless parameter check in btuart_hci_send_frame()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6b5924bfeac1321118fbc54313fc3c25ba1a2cb5;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Remove pointless parameter check in btuart_hci_send_frame()

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