Bluetooth: hidp: using strlcpy instead of strncpy, also beautify code.
For NULL terminated string, need always let it ended by zero. Since have already called memcpy() to initialize 'ci', so need not redundant initialization. Better use ''if(session->hid) {} else if(session->input) {}"" instead of ''if(session->hid) {}; if(session->input) {};'' Signed-off-by: Chen Gang <gang.chen@asianux.com> Reviewed-by: David Herrmann <dh.herrmann@gmail.com> Acked-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
