From 07dc93dd14957dc1faba08f0aadd27b082e35ba2 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 19 Apr 2013 10:14:51 +0300 Subject: Bluetooth: Fix HCI command send functions to use const specifier All HCI command send functions that take a pointer to the command parameters do not need to modify the content in any way (they merely copy the data to an skb). Therefore, the parameter type should be declared const. This also allows passing already const parameters to these APIs which previously would have generated a compiler warning.
