From: Philipp Hachtmann Date: Mon, 17 Aug 2015 15:31:46 +0000 (+0200) Subject: USB: symbolserial: Use usb_get_serial_port_data X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=951d3793bbfc0a441d791d820183aa3085c83ea9;p=linux-beck.git 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.
