Subject: patch "USB: symbolserial: Use usb_get_serial_port_data" added to usb-next
Date: Tue, 18 Aug 2015 20:09:56 -0700 [thread overview]
Message-ID: <143995379634108@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
USB: symbolserial: Use usb_get_serial_port_data
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-next 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 also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: USB: symbolserial: Use usb_get_serial_port_data
The driver used usb_get_serial_data(port->serial) which compiled but resulted
in a NULL pointer being returned (and subsequently used). I did not go deeper
into this but I guess this is a regression.
