Fwd: Intel 7560 LTE Modem stops working after resuming from standby

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

I noticed a few days ago, after Fedora moved to Kernel 6.5, that my Intel LTE Modem was not working anymore after resuming from standby. 

The journal listed this error message multiple times:
kernel: iosm 0000:01:00.0: msg timeout

It took me a while to determine the root cause of the problem, since the modem did not work either in the following warm reboots. 
Only a shutdown revived the modem.

I did a bisection of the error and I was able to find the culprit:

[e4f5073d53be6cec0c654fac98372047efb66947] net: wwan: iosm: enable runtime pm support for 7560

See Bugzilla for the full thread.

Anyway, I'm adding this regression to regzbot:

#regzbot introduced: e4f5073d53be6c https://bugzilla.kernel.org/show_bug.cgi?id=217996
#regzbot title: pm support for Intel 7560 makes the modem stops working after resume

Thanks.
