From 1d738dbb252f66dd909a662d85c67b93314d7ae7 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 22 May 2025 16:37:25 -0700 Subject: [PATCH 4330/5403] drm/gpu: Remove dead checks on wbinvd_on_all_cpus()'s return value Remove the checks and associated pr_err() on wbinvd_on_all_cpus() failure, as the helper has unconditionally returned 0/success since commit caa759323c73 ("smp: Remove smp_call_function() and on_each_cpu() return values").
