Not strictly needed here, but a sensible change and it makes reordring my CXL staging tree a lot simpler. Based-on: [PATCH qemu 0/4] hw/cxl: Add support for scan media Message-id: 20240705120643.959422-1-Jonathan.Cameron@huawei.com Add support for the feature commands, device patrol scrub control and DDR5 ECS control features. CXL spec 3.1 section 8.2.9.6 describes optional device specific features. CXL spec 3.1 section 8.2.9.9.11.1 describes the device patrol scrub control feature. CXL spec 3.1 section 8.2.9.9.11.2 describes the DDR5 Error Check Scrub (ECS) control feature. This series is one of the test vehicles for the support of RAS feature control in Linux and having it upstream would be useful to support that work. There are also a lot more 'features' using the feature infrastructure that are dependent on the first 2 patches.
