Subject: patch "staging: vt6656: Power save stop wake_up_count wrap around." added to staging-linus
Date: Thu, 16 Apr 2020 13:50:34 +0200 [thread overview]
Message-ID: <158703783434197@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
staging: vt6656: Power save stop wake_up_count wrap around.
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: vt6656: Power save stop wake_up_count wrap around.
conf.listen_interval can sometimes be zero causing wake_up_count
to wrap around up to many beacons too late causing
CTRL-EVENT-BEACON-LOSS as in.
wpa_supplicant[795]: message repeated 45 times: [..CTRL-EVENT-BEACON-LOSS ]
