Subject: [PATCH 15/23] cxl/pci: Use module_pci_driver
Date: Mon, 09 Aug 2021 15:29:07 -0700	[thread overview]
Message-ID: <162854814754.1980150.2021179816870547130.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <162854806653.1980150.3354618413963083778.stgit@dwillia2-desk3.amr.corp.intel.com>

Now that cxl_mem_{init,exit} no longer need to manage debugfs, switch
back to the smaller form of the boiler plate.
