From 595abbaff5db121428247a2e6ab368734472e101 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 20 Feb 2020 20:03:50 -0800 Subject: y2038: remove ktime to/from timespec/timeval conversion A couple of helpers are now obsolete and can be removed, so drivers can no longer start using them and instead use y2038-safe interfaces.
