From 3fa9f553c0c0418b9abf93c2f33a44c98380beaf Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 15 Mar 2021 17:25:16 +1300 Subject: [PATCH] dm: core: Adjust uclass setup with of-platdata When OF_PLATDATA_INST is enabled we don't need to create the uclass list. Instead we just need to point to the existing list. Update the code accordingly.
