From 029b18361921a0a07b17bd89a2cf20df3d115de8 Mon Sep 17 00:00:00 2001 From: Gabriel Laskar Date: Sun, 11 Jan 2015 16:18:06 -0800 Subject: Input: uinput - fix ioctl nr overflow for UI_GET_SYSNAME/VERSION Request number for ioctls are encoded as 8bit numbers, but unfortunately UI_GET_SYSNAME and UI_GET_VERSION specifu values larger than that, so they get truncated to 44 (0x2c) and 45 (0x2d). This change makes requested values match their effective values (the ABI stays intact).
