From 553bd29700145e1849698985e9800f14e967da49 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Tue, 7 Feb 2023 12:05:29 +0100 Subject: [PATCH] of: device: Ignore modalias of reused nodes If of_node is reused, do not use that node's modalias. This will hide the name of the actual device. This is rather prominent in USB glue drivers creating a platform device for the host controller.
