The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >>From 951d3793bbfc0a441d791d820183aa3085c83ea9 Mon Sep 17 00:00:00 2001 From: Philipp Hachtmann Date: Mon, 17 Aug 2015 17:31:46 +0200 Subject: 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.
