mei: Move uuid.h to the MEI namespace

2023-03-23T16:25:46Z

There is only a single user of the UUID uAPI, let's make it part of that user. The way it's done is to prevent compilation time breakage for the user space that does #include In the future MEI user space tools can switch over to use mei_uuid.h.

misc/mei/hdcp: Use correct macros to initialize uuid_le

GUID_INIT() is for internal guid_t type and shouldn't be used for the uuid_le. I.o.w. relying on the implementation details is layering violation. Use correct macros to initialize uuid_le.

misc/mei: Add NULL check to component match callback functions

2022-04-29T09:17:22Z

Currently, component_match callback functions used in mei refers to the driver name, assuming that the component device being matched has a driver bound. It can cause a NULL pointer dereference when a device without a driver bound registers a component. This is due to the nature of the component framework where all registered components are matched in any component_match callback functions. So even if a component is registered by a totally irrelevant device, that component is also shared to these callbacks for i915 driver. To prevent totally irrelevant device being matched for i915 and causing a NULL pointer dereference for checking driver name, add a NULL check on dev->driver to check if there is a driver bound before checking the driver name. In the future, the string compare on the driver name, "i915" may need to be refactored too.
