From: Raag Jadav Date: Tue, 2 Jun 2026 04:48:42 +0000 (+0530) Subject: drm/xe/drm_ras: Make counter allocation drm managed X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=4dcfcdc9fbb5efef21e149adf349d42d84c9da04;p=thirdparty%2Fkernel%2Flinux.git drm/xe/drm_ras: Make counter allocation drm managed cleanup_node_param() is not registered for previous node in case of counter allocation failure, which results in stale memory of previous node that isn't cleaned up on unwind. Fix this using drm managed allocation, which is guaranteed to be cleaned up on unwind.
