Let's not be alarmed if we reach a timeout while waiting for FLR resets and print debugs rather than errors. The function is anyway a void fucntions without any effect. While at it, increase the timeout. Thanks, Andi Andi Shyti (2): drm/i915: Increase FLR timeout from 3s to 9s drm/i915: Don't treat FLR resets as errors drivers/gpu/drm/i915/intel_uncore.c | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-)
