[PATCH 6.1 028/185] parisc/power: Fix power soft-off button emulation on qemu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-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")
