* mei: hdcp: match without driver nameAlexander Usyskin2024-01-301-2/+12
| | | | | | | | | | | | Xe driver uses this component too, but current match function matches by i915 driver name. Remove dependency on i915 driver name in component_match function. Use PCI header information to match Intel graphics device.

* misc/mei: Add NULL check to component match callback functionsWon Chung2022-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver core ignores the return value of mei_cl_device_remove() so passing an error value doesn't solve any problem. As most mei drivers' remove callbacks return 0 unconditionally and returning a different value doesn't have any effect, change this prototype to return void and return 0 unconditionally in mei_cl_device_remove().

| | | | | | | | | | | | | | | | | | | | | | | | There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Also, make use of the array_size() helper instead of the open-coded version in memcpy(). These sorts of multiplication factors need to be wrapped in array_size(). And while there, use the preferred form for passing a size of a struct. The alternative form where struct name is spelled out hurts readability and introduces an opportunity for a bug when the pointer variable type is changed but the corresponding sizeof that is passed as argument is not.

* misc/mei/hdcp: Client driver for HDCP applicationRamalingam C2019-02-251-0/+64
ME FW contributes a vital role in HDCP2.2 authentication. HDCP2.2 driver needs to communicate to ME FW for each step of the HDCP2.2 authentication. ME FW prepare and HDCP2.2 authentication parameters and encrypt them as per spec. With such parameter Driver prepares HDCP2.2 auth messages and communicate with HDCP2.2 sink. Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and verification. Once All the steps of HDCP2.2 authentications are complete on driver's request ME FW will configure the port as authenticated and supply the HDCP keys to the Gen HW for encryption. Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption for a port. ME FW is interfaced to kernel through MEI Bus Driver.
