Subject: Re: [RFC PATCH] drivers core: cpu: add hotplug callback to update
 cpu_dev state to resumed

FWIW the "cache: parent cpuN should not be sleeping" warnings no longer
appear during s2ram procedure on R-Car H3-ES20 Salvator-X with this patch.
The kernel version is v5.0-rc3-241-g7c2614bf7a1f.
The test procedure is:

root@...vator-x:~# modprobe i2c-dev
root@...vator-x:~# i2cset -f -y 7 0x30 0x20 0x0F
root@...vator-x:~# echo deep > /sys/power/mem_sleep
root@...vator-x:~# echo mem > /sys/power/state

Tested-by: Eugeniu Rosca <erosca@...adit-jv.com>
