Subject: [RFC PATCH v2 04/28] cxl: Add helper for new drivers
Date: Fri, 22 Oct 2021 11:36:45 -0700	[thread overview]
Message-ID: <20211022183709.1199701-5-ben.widawsky@intel.com> (raw)
In-Reply-To: <20211022183709.1199701-1-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.
