From 52bc423a7e74f5d1dac3ab61e742831e004b8e39 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 11 Oct 2013 07:01:03 -0700 Subject: [PATCH] Bluetooth: Remove pointless parameter check in hci_uart_send_frame() The hdev parameter of hci_uart_send_frame() is always valid. If it were not valid, then it would have crashed earlier in the call chain.
