The individual sensor drivers implemented in the ISH firmware needs
capability to take special actions when there is a change in the system
standby state. The ISH core firmware passes this notification to
individual sensor drivers in response to the OS request via connected
standby bit in the SYSTEM_STATE_STATUS command.
This change sets CONNECTED_STANDBY_STATE_BIT bit to 1 during suspend
callback and clears during resume callback.

I was looking for this patch in 5.13-rc2. It is not there, Is there
some pull request pending?
Thanks,

I don't see this patch in 5.13-rc3. But I see in linux-next. There are
other patches here which didn't make to 5.13-rc.
I see them in
https://kernel.googlesource.com/pub/scm/linux/kernel/git/hid/hid/+/refs/heads/for-5.13/intel-ish
Did you decide to postpone for 5.14? It will be fine to postpone.
Thanks,
Srinivas

Uwe Kleine-Koening already noticed this:
http://lore.kernel.org/r/nycvar.YFH.7.76.2105131318120.28378@cbobk.fhfr.pm
I apologize for the hassle.

Thanks. It's currently in for-5.14/intel-ish.
