From d0fad89da9801b3945d2ee7243ecbc75b3da6f09 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 12 May 2011 16:50:09 -0700 Subject: Bluetooth: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following warning: In function 'copy_from_user', inlined from 'rfcomm_sock_setsockopt' at net/bluetooth/rfcomm/sock.c:705: arch/x86/include/asm/uaccess_64.h:65: warning: call to 'copy_from_user_overflow' declared with attribute warning: copy_from_user() buffer size is not provably correct presumably due to buf_size being signed causing GCC to fail to see that buf_size can't become negative.
