6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@xxxxxx>
commit 6472036581f947109b20664121db1d143e916f0b upstream.
Make sure to start the kthread to check the power button on qemu as
well if the power button address was provided.
This fixes the qemu built-in system_powerdown runtime command.
Fixes: d0c219472980 ("parisc/power: Add power soft-off when running on qemu")
