Subject: [PATCH 2/7] drm/i915/guc: Only assign guc_id.id when stealing guc_id
Date: Fri, 10 Dec 2021 16:56:07 -0800	[thread overview]
Message-ID: <20211211005612.8575-3-matthew.brost@intel.com> (raw)
In-Reply-To: <20211211005612.8575-1-matthew.brost@intel.com>

Previously assigned whole guc_id structure (list, spin lock) which is
incorrect, only assign the guc_id.id.

Fixes: 0f7976506de61 ("drm/i915/guc: Rework and simplify locking")
