Subject: Bluetooth: Remove pointless parameter check in bfusb_send_frame()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aae26277121a99509300c8024cf88d313f18f367;p=linux-beck.git

Bluetooth: Remove pointless parameter check in bfusb_send_frame()

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