Subject: [PATCH v5 2/6] PCI: Export pci_set_target_speed()
Date: Wed, 19 Aug 2026 18:55:53 +0530 [thread overview]
Message-ID: <20260819-bwscale-v5-2-6dea79786b37@oss.qualcomm.com> (raw)
In-Reply-To: <20260819-bwscale-v5-0-6dea79786b37@oss.qualcomm.com>
Export pci_set_target_speed() so that other kernel drivers can use it
to change the PCIe data rate.
