From c6e8418521a8fd2068ade2c6a1514315c99cc717 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 11 Jan 2023 12:30:16 +0100 Subject: xen/xenbus: move to_xenbus_device() to use container_of_const() The driver core is changing to pass some pointers as const, so move to_xenbus_device() to use container_of_const() to handle this change. to_xenbus_device() now properly keeps the const-ness of the pointer passed into it, while as before it could be lost.
