Subject: drm/xen-front: Make structure fb_funcs constant
Git-commit: d777478599f781fc5162d1ae95dbee6e5ae05a41
Patch-mainline: v5.4-rc1
References: bsc#1152472

Static structure fb_funcs, of type drm_framebuffer_funcs, is used only
when it is passed to drm_gem_fb_create_with_funcs() as its last
argument. drm_gem_fb_create_with_funcs does not modify its lst argument
(fb_funcs) and hence fb_funcs is never modified. Therefore make fb_funcs
constant to protect it from further modification.
Issue found with Coccinelle.
