Subject: [PATCH 1/2] ACPI: pfr_telemetry: use ACPI_FREE() to free acpi_object
Date: Fri, 18 Nov 2022 14:32:18 +0800	[thread overview]
Message-ID: <20221118063219.2612473-2-bobo.shaobowang@huawei.com> (raw)
In-Reply-To: <20221118063219.2612473-1-bobo.shaobowang@huawei.com>

acpi_evaluate_dsm_typed()/acpi_evaluate_dsm() should be coupled
with ACPI_FREE() to free the ACPI memory, because we need to
track the allocation of acpi_object when ACPI_DBG_TRACK_ALLOCATIONS
enabled, so use ACPI_FREE() instead of kfree().

Fixes: b0013e037a8b ("ACPI: Introduce Platform Firmware Runtime Telemetry driver")
