From 5c7d2dd2852c7cd8f07cf91291b351c01b781044 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sat, 4 Apr 2015 20:59:40 -0700 Subject: [PATCH] Bluetooth: Make data pointer of hci_recv_stream_fragment const The data pointer provided to hci_recv_stream_fragment function should have been marked const. The function has no business in modifying the original data. So fix this now.
