Subject: [PATCH v3 08/12] PCI/ASPM: Remove struct aspm_register_info.l1ss_ctl2 (unused)
Date: Thu, 15 Oct 2020 14:30:35 -0500	[thread overview]
Message-ID: <20201015193039.12585-9-helgaas@kernel.org> (raw)
In-Reply-To: <20201015193039.12585-1-helgaas@kernel.org>

From: Bjorn Helgaas <bhelgaas@google.com>

We never use the aspm_register_info.l1ss_ctl2 value, so remove it.  No
functional change intended.
