From 7bd9c9f962eb36d5b88bbe4108d368aad3500c05 Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Thu, 21 Mar 2024 12:55:12 -0700 Subject: [PATCH] drm/xe/guc: Check error code when initializing the CT mutex The initialization via drmm_mutex_init can fail, so we need to check the return code and escalate the failure. The mutex initialization has been moved after all the other init steps that can't fail, so we're always guaranteed to have those done and don't have to check in the cleanup code.
