commit ac547f0bedca85525b7dccc7acfbd58916407ccf Author: Michal Orzel <michal.orzel@xxxxxxx> AuthorDate: Thu Aug 10 13:25:43 2023 +0200 Commit: Stefano Stabellini <stefano.stabellini@xxxxxxx> CommitDate: Thu Aug 10 19:29:02 2023 -0700 xen/arm: Fix initrd placeholders generation in make_chosen_node() When booting a dom0less domU without initial ramdisk, it was observed that Xen still creates empty linux,initrd-{start,end} properties under /chosen node. This is because in make_chosen_node(), generation of initrd placeholders (later on filled with the real values) is protected with a check for presence of kernel bootmodule (always present) instead of initrd bootmodule. Fix it along with renaming the variable from "mod" to "initrd" to prevent similar mistakes in the future.
