From d160c66cda0ac8614adc53a5b5b0e6d6f1a05a5b Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Mon, 5 Feb 2024 12:30:22 +0200 Subject: [PATCH] net: Do not return value from init_dummy_netdev() init_dummy_netdev() always returns zero and all the callers do not check the returned value. Set the function to not return value, as it is not really used today.
