Subject: [PATCH v2 14/15] cxl/pmem: Convert nvdimm bridge API to use memdev
Date: Wed, 12 Jan 2022 15:47:48 -0800	[thread overview]
Message-ID: <20220112234749.1965960-15-ben.widawsky@intel.com> (raw)
In-Reply-To: <20220112234749.1965960-1-ben.widawsky@intel.com>

The cxl_pmem driver specific cxl_nvdimm structure isn't a suitable
parameter for an exported API that can be used by other drivers.
Instead, use a memdev structure, which should be woven into any caller
using this API.
