Subject: [PATCH next-queue v6 1/4] Revert "PCI: Make pci_enable_ptm() private"
Date: Mon, 26 Jul 2021 20:36:54 -0700	[thread overview]
Message-ID: <20210727033657.39885-2-vinicius.gomes@intel.com> (raw)
In-Reply-To: <20210727033657.39885-1-vinicius.gomes@intel.com>

Make pci_enable_ptm() accessible from the drivers.

Exposing this to the driver enables the driver to use the
'ptm_enabled' field of 'pci_dev' to check if PTM is enabled or not.

This reverts commit ac6c26da29c1 ("PCI: Make pci_enable_ptm() private").
