From: Phil Sutter <psutter@xxxxxxxxxx> redhat: Add mark_driver_deprecated() Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1945179 Upstream Status: RHEL-only Allow marking drivers deprecated. The printed message is basically identical to what mark_hardware_deprecated() prints but generalized a bit to cover non-hardware drivers also. Semantically, the introduced function aligns with mark_driver_unsupported().
