From 8ad9268216ee022e39ee8c58499c3a7947489d0a Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 14 Nov 2022 09:13:45 +0100 Subject: [PATCH] phy: qcom-qmp-combo: fix runtime suspend commit 70a219e8f400d7a63c95c5433d8b2c052d562df4 upstream. Drop the confused runtime-suspend type check which effectively broke runtime PM if the DP child node happens to be parsed before the USB child node during probe (e.g. due to order of child nodes in the devicetree). Instead use the new driver data USB PHY pointer to access the USB configuration and resources.
