[PATCH AUTOSEL 4.19 21/23] drm/amd/display: make flip_timestamp_in_us a 64-bit variable
From: Sasha Levin
Date: Mon Jan 22 2024 - 11:46:51 EST
From: Josip Pavic <josip.pavic@xxxxxxx>
[ 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.
