[PATCH 3.4 137/172] USB: ftdi_sio: Use jtag quirk for SNAP Connect E10

From: lizf
Date: Tue Jun 16 2015 - 05:05:03 EST


From: Doug Goldstein <cardoe@xxxxxxxxxx>

3.4.108-rc1 review patch. If anyone has any objections, please let me know.

------------------


commit b229a0f840f774d29d8fedbf5deb344ca36b7f1a upstream.

This patch uses the existing CALAO Systems ftdi_8u2232c_probe in order
to avoid attaching a TTY to the JTAG port as this board is based on the
CALAO Systems reference design and needs the same fix up.
