Subject: drm/msm: avoid using 'timespec'
Git-commit: 6cedb8b377bba6520508399b74754b9a0ca06edf
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The timespec structure and associated interfaces are deprecated and will
be removed in the future because of the y2038 overflow.
The use of ktime_to_timespec() in timeout_to_jiffies() does not
suffer from that overflow, but is easy to avoid by just converting
the ktime_t into jiffies directly.
