This is a note to let you know that I've just added the patch titled
usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to
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-testing 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 be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to
imx6ul
According to the i.MX6UL Errata document:
https://www.nxp.com/docs/en/errata/IMX6ULCE.pdf
ERR007881 also affects i.MX6UL, so pass the
CI_HDRC_DISABLE_DEVICE_STREAMING flag to workaround the issue.
