stable inclusion from stable-v6.6.33 commit 81c52c0ccc6ae2ff9e0911b4a2409ab4516bc246 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 12870ae3818e39ea65bf710f645972277b634f72 ]
It's not an error or exceptional situation when the hosting environment does not expose a name for the LP/guest via RTAS or the device tree. This happens with qemu when run without the '-name' option. The message also lacks a newline. Remove it.
