Looks good to me .. the reliance on implicit selections is something
that we've been trying to squash over the years, and this is exactly
why!

I've merged the change, SRCREV updates to follow shortly.

[linux-yocto] [PATCH 1/1] features/ftrace: set CONFIG_FTRACE=y

[California Sullivan]

With EXPERT, EMBEDDED and DEBUG_KERNEL removed from the base, this
is no longer being selected by default in in standard BSPs, causing
breakage in things that relied on it.

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.

Bruce



Best Regards

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
