From 9f041c5d8296b3a04cf3ead473a124fb538490dc Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 21 Nov 2022 10:46:49 +0100 Subject: [PATCH] driver core: pass a const * into of_device_uevent() of_device_uevent() does not modify the struct device * passed into it, so make it a const * to enforce this. Also the documentation for the function was really wrong so fix that up at the same time.
