Subject: [PATCH v6 21/21] ACPI: Remove the unused find_acpi_cpu_cache_topology()
Date: Mon, 4 Jul 2022 11:16:05 +0100 [thread overview]
Message-ID: <20220704101605.1318280-22-sudeep.holla@arm.com> (raw)
In-Reply-To: <20220704101605.1318280-1-sudeep.holla@arm.com>
The sole user of this find_acpi_cpu_cache_topology() was arm64 topology
which is now consolidated into the generic arch_topology without the need
of this function.
Drop the unused function find_acpi_cpu_cache_topology().
