From 108157c468eed8291c866415b8708eb2a8735dc4 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Wed, 24 Feb 2021 17:40:41 +0100 Subject: [PATCH] net: dsa: remove NULL check for priv and platform data Because the uclass has the "*_auto" properties set, the driver model will take care of allocating the private structures for us and they can't be NULL. Drop the checks.
