Subject: patch "USB: chipidea: msm: fix ulpi-node lookup" added to usb-linus
Date: Tue, 19 Dec 2017 16:01:49 +0100 [thread overview]
Message-ID: <15136957096725@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
USB: chipidea: msm: fix ulpi-node lookup
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.

Subject: USB: chipidea: msm: fix ulpi-node lookup
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.
Note that the original premature free of the parent node has already
been fixed separately, but that fix was apparently never backported to
stable.
