Subject: patch "Revert "usb: cdc-wdm: Fix a sleep-in-atomic-context bug in" added to usb-linus
Date: Thu, 20 Sep 2018 12:47:53 +0200 [thread overview]
Message-ID: <15374404735163@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
Revert "usb: cdc-wdm: Fix a sleep-in-atomic-context bug in
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-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.
