From f8db89d14efb770dd59aa0ca74386e5de68310d5 Mon Sep 17 00:00:00 2001 From: Prashant Malani Date: Mon, 10 Feb 2020 11:06:24 -0800 Subject: mfd: cros_ec: Check DT node for usbpd-notify add Add a check to ensure there is indeed an EC device tree entry before adding the cros-usbpd-notify device. This covers configs where both CONFIG_ACPI and CONFIG_OF are defined, but the EC device is defined using device tree and not in ACPI.
