Subject: [PATCH] input: Make use of timeval portable for 64bit time_t
This patch avoids using time field of input_event structure which is not available
on 32bit arches supporting 64bit time_t structs, Patch makes it compatible with new
and keeps old input.h implementation functional as well.
See https://sourceware.org/glibc/wiki/Y2038ProofnessDesign
Upstream-Status: Submitted [https://codereview.qt-project.org/c/qt/qtbase/+/282610]
