Subject: [RFC PATCH 04/27] cxl: Add helper for new drivers
Date: Fri, 15 Oct 2021 22:15:08 -0700	[thread overview]
Message-ID: <20211016051531.622613-5-ben.widawsky@intel.com> (raw)
In-Reply-To: <20211016051531.622613-1-ben.widawsky@intel.com>

Many CXL drivers simply want to register and unregister themselves.
module_driver already supported this. A simple wrapper around that
reduces a decent amount of boilerplate in upcoming patches.
