From 5cea4b474e12cdfcd969ba098ee2544198771b51 Mon Sep 17 00:00:00 2001 From: Philipp Hachtmann Date: Mon, 17 Aug 2015 17:31:46 +0200 Subject: [PATCH] USB: symbolserial: Use usb_get_serial_port_data commit 951d3793bbfc0a441d791d820183aa3085c83ea9 upstream. 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.
