Subject: [PATCH AUTOSEL 5.10 35/43] xen: flag xen_drm_front to be not essential for system boot

From: Juergen Gross <jgross@...e.com>

[ Upstream commit 1c669938c31b6e2a0d5149c3c6257ca9df6cb100 ]

Similar to the virtual frame buffer (vfb) the pv display driver is not
essential for booting the system. Set the respective flag.
