This is a note to let you know that I've just added the patch titled
USB: serial: cp210x: Fixed usb_control_msg timeout values
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 will 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: serial: cp210x: Fixed usb_control_msg timeout values
Fixed too small hardcoded timeout values for usb_control_msg
in driver for SiliconLabs cp210x-based usb-to-serial adapters.
Replaced with USB_CTRL_GET_TIMEOUT/USB_CTRL_SET_TIMEOUT.
