Subject: [PATCH v2] Bluetooth: hidp: using strlcpy instead of strncpy, also beautify code.
Date: Wed, 08 May 2013 11:34:30 +0800 [thread overview]
Message-ID: <5189C7C6.8090408@asianux.com> (raw)
In-Reply-To: <5189A417.503-bOixZGp5f+dBDgjK7y7TUQ@public.gmane.org>
For NUL terminated string, need always let it ended by zero.
Since have already called memcpy() to initialize 'ci', so need not
redundent initializations.
Better use ''if(session->hid) {} else if(session->input) {}'' instead
of ''if(session->hid) {}; if(session->input) {};''
