Subject: patch "usb: typec: ucsi: Increase command completion timeout value" added to usb-linus
Date: Sun, 22 Apr 2018 14:57:12 +0200 [thread overview]
Message-ID: <152440183214133@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: typec: ucsi: Increase command completion timeout value
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: typec: ucsi: Increase command completion timeout value
On some boards, under heavy load, the EC firmware is
unable to complete commands even in one second. Increasing
the command completion timeout value to five seconds.
