Subject: udlfb: Make dlfb_ops constant
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=df5eff6d2a44c8f01b0dcd61b0ed5715116e10b4;p=openwrt%2Fstaging%2Fblogic.git

udlfb: Make dlfb_ops constant

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.
