net: caif: use strlcpy() instead of strncpy()
gcc-8 reports net/caif/caif_dev.c: In function 'caif_enroll_dev': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' output may be truncated copying 15 bytes from a string of length 15 [-Wstringop-truncation] net/caif/cfctrl.c: In function 'cfctrl_linkup_request': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' output may be truncated copying 15 bytes from a string of length 15 [-Wstringop-truncation] net/caif/cfcnfg.c: In function 'caif_connect_client': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' output may be truncated copying 15 bytes from a string of length 15 [-Wstringop-truncation] The compiler require that the input param 'len' of strncpy() should be greater than the length of the src string, so that '\0' is copied as well. We can just use strlcpy() to avoid this warning. Signed-off-by: Xiongfeng Wang <xiongfeng.wang@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
