Subject: udlfb: Make dlfb_ops constant
Git-commit: df5eff6d2a44c8f01b0dcd61b0ed5715116e10b4
Patch-mainline: v5.4-rc1
References: bsc#1152472
Static structure dlfb_ops, of type fb_ops, is not used except to be
copied into another variable. Hence make dlfb_ops constant to protect it
from unintended modification.
Issue found with Coccinelle.
