From 14cfde84e33e0c5bbb8c30e0c309c29e92d4118a Mon Sep 17 00:00:00 2001 From: xinhui pan Date: Tue, 9 Apr 2019 16:53:08 +0800 Subject: [PATCH] drm/amdgpu: Add a check to avoid panic because of unexpected irqs IP initialize ras in late_init, because of the BUGs of PSP or any other components, driver receives unexpected irqs. It is ok to add such check anyway.
