From efc9812edc61761708e6e703a48ed18e1af6bd12 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Thu, 4 Feb 2021 17:17:08 +0300 Subject: [PATCH] usb: dwc3: haps: Constify the software node What platform_device_add_properties() does is it allocates dynamically a software node that will contain the device properties supplied to it, and then couples that node with the device. Since that node is always created, it might as well be constant.
