From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Johan Hedberg To: linux-bluetooth@vger.kernel.org Subject: [PATCH] Bluetooth: Fix endianness handling of cmd_status/complete opcodes Date: Sat, 9 Mar 2013 09:53:50 +0200 Message-Id: <1362815630-6800-1-git-send-email-johan.hedberg@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Johan Hedberg The opcode in cmd_complete and cmd_status events is 16 bits, so we should only be comparing it after having converted it to the host endianness. There's already an opcode variable in both functions which is in host endiannes so the right fix is to just start using it instead of ev->opcode.
