Subject: [PATCH] drm/i915: free _DSM package when no connectors
Date: Fri, 9 Jan 2026 08:55:49 +0530 [thread overview]
Message-ID: <20260109032549.1826303-1-kaushlendra.kumar@intel.com> (raw)
acpi_evaluate_dsm_typed() returns an ACPI package in pkg.
When pkg->package.count == 0, we returned without freeing pkg,
leaking memory. Free pkg before returning on the empty case.
