Subject: [PATCH AUTOSEL 5.15 30/35] drm/amd/display: make flip_timestamp_in_us a 64-bit variable
From: Josip Pavic <josip.pavic@....com>
[ Upstream commit 6fb12518ca58412dc51054e2a7400afb41328d85 ]
[Why]
This variable currently overflows after about 71 minutes. This doesn't
cause any known functional issues but it does make debugging more
difficult.
[How]
Make it a 64-bit variable.
