Subject: Ensure device is closed before usb_get_port_path()
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=7bbe5a2b6a3cea7bc5b59ca3c34ed4f6fcf8c3b1

Ensure device is closed before usb_get_port_path()

The usb_get_port_path() function opens the passed device on FreeBSD,
which fails if the device has already been open.

This fixes bug #1109.
