From 62a35e81c2c1bae04fdefde56f2a92dd3e56164d Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 29 Jun 2020 11:19:21 -0700 Subject: [PATCH] drm/msm: Quiet error during failure in optional resource mappings. We don't expect to find vbif_nrt or regdma on sdm845, but were clogging up dmesg with errors about it.
