This commit adds missing configuration of MBUS windows access protection in mvneta_conf_mbus_windows function - a dedicated variable for that purpose remained there unused since v3.8 initial mvneta support. Because of that the register contents were inherited from the bootloader.

If not, then I am not sure it qualifies for stable.
Indeed, it's not fixing a visible thing, unless you resume from suspend to ram. However, the original driver declares and updates 'win_protect ' variable, which have remained unused for past 3 years:) If you think it's not worth cc'ing stable despite that, I will remove the notification.

Ok.

Indeed, my mistake. Thanks, Marcin
