From: Xiongfeng Wang <xiongfeng.wang@xxxxxxxxxx> gcc-8 reports drivers/iio/accel/st_accel_i2c.c: In function 'st_accel_i2c_probe': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified bound 20 equals destination size [-Wstringop-truncation] The compiler require that the length of the dest string is greater than the length we want to copy to make sure the dest string is nul-terminated. We can just use strlcpy() to avoid this warning.
