From 2e746942ebacf1565caa72cf980745e5ce297c48 Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Sun, 13 Jan 2019 22:28:05 -0800 Subject: Input: input_event - provide override for sparc64 The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier. Fix the typo, and provide an override for sparc64.

The Stratus Duo ships with a USB dongle to enable wireless connectivity, but it can also function as a wired controller by connecting it directly to a PC via USB, hence the need for two USD PIDs. 0x1430 is the dongle, and 0x1431 is the controller.
