Hi Bruce Ashfield,
Thanks.
I find that SRCREV update for 4.1 has been done.
When will SRCREV update for 4.4 be done?
All the patches have been sent, they are likely still in the process
of being merged. When they actually get into oe-core is out of my
control.
Bruce
Best Regards

Hi Bruce Ashfield,
Our system platform will use linux-yocto-4.4.
Therefore, Sending the patch again, It is for linux-yocto-4.4.
Thanks.
I've merged the change to the 4.4 tree. SRCREV updates will follow in a few
days, but if you adjust SRCREVs yourself, you can use it now.

Subject: [PATCH] iwlwifi: mvm: don't allow sched scans without
matches to be started
commit 5e56276e7555b34550d51459a801ff75eca8b907 upstream.
The firmware can perform a scheduled scan with not matchsets passed,
but it can't send notification that results were found. Since the
userspace then cannot know when we got new results and the firmware
wouldn't trigger a wake in case we are sleeping, it's better not to allow scans
without matchsets.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=110831
