Subject: [PATCH v3 18/28] cxl/pci: Use module_pci_driver
Date: Tue, 24 Aug 2021 09:07:02 -0700	[thread overview]
Message-ID: <162982122234.1124374.8206618857845373193.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <162982112370.1124374.2020303588105269226.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.

Acked-by: Ben Widawsky <ben.widawsky@intel.com>
