From 718551bbed3ca5308a9f9429305dd074727e8d46 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 1 Jun 2023 10:38:04 -0700 Subject: [PATCH] drm/i915: Fix error handling if driver creation fails during probe If i915_driver_create() fails to create a valid 'i915' object, we should just disable the PCI device and return immediately without trying to call i915_probe_error() that relies on a valid i915 pointer.
