From: Dima Stepanov <dmitrii.stepanov@xxxxxxxxxxxxxxx> During checkpatch analyzing the following warning message was found: WARNING:STRLCPY: Prefer strscpy over strlcpy - see: https://lore.kernel.org/r/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@xxxxxxxxxxxxxx/ Fix it by using strscpy calls instead of strlcpy.
