Subject: Fix free() of uninitialized pointer.
X-Git-Tag: libserialport-0.1.1~88
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=e31f2c6b8b8f2b7e554df911cc9a3482b99632b4;p=libserialport.git

Fix free() of uninitialized pointer.

Explicitly set port->usb_path to NULL, otherwise a free(port->usb_path)
can happen where port->usb_path is uninitialized.

This closes bug #512.
