From 413db06c05e729639e9b64cf7ab5d918b8182006 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 28 Oct 2022 18:04:29 +0200 Subject: phy: qcom-qmp-usb: clean up probe initialisation Stop abusing the driver data pointer and instead pass the driver state structure directly to the initialisation helpers during probe.
