Ah, yes. I will revise the copyrights in Redfish.fdf.inc and RedfishComponents.dsc.inc when merge it.
Thanks for catching this.

Looks good to me. But for the copyright, I think it would be "2020-2021", right?
For example:

Subject: [edk2-devel] [PATCH] RedfishPkg/RedfishConfigHandler: EDKII
RedfishConfigHandler Protocol

The driver is used to manage EDK2 Redfish Configuration Handler
Protocol installed by EDK2 Redfish feature drivers.
This is the EDK2 Redfish client driver written based on the EDK2
Redfish foundation to initialize EDK2 Redfish feature drivers.

EDK2 Redfish feature drivers are used to provision/consume/update
the firmware owns Redfish properties during system power on
initialization.

RedfishConfigHandlerCommon.c has the common code for the driver
instances used in different EDK2 boot phases or used by different
driver models in the future contribution.

attached to

boot times, the tests

possible to execute. This

function must be aware that the
+ device specified by ControllerHandle may already be managed by the
same driver or a
+ different driver. This function must match its calls to AllocatePages() with
FreePages(),
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because ControllerHandle may have been previously started by the same
driver, if a protocol is
+ already in the opened state, then it must not be closed with
CloseProtocol(). This is required

device path. This
+ parameter is ignored by device drivers, and is optional for
bus

specified
+ by ControllerHandle and the child controller specified
+ by RemainingDevicePath are both supported by this

+ Tests to see if this driver supports a given controller. If a child device is
provided,

specified child device.
+
+ This function checks to see if the driver specified by This supports the
device specified by
+ ControllerHandle. Drivers will typically use the device path attached to
+ ControllerHandle and/or the services from the bus I/O abstraction
attached to
+ ControllerHandle to determine if the driver supports ControllerHandle.

+ may be called many times during platform initialization. In order to reduce
boot times, the tests
+ performed by this function must be very small, and take as little time as
possible to execute. This
+ function must not change the state of any hardware devices, and this
function must be aware that the
+ device specified by ControllerHandle may already be managed by the
same driver or a
+ different driver. This function must match its calls to AllocatePages() with
FreePages(),
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because ControllerHandle may have been previously started by the same
driver, if a protocol is
+ already in the opened state, then it must not be closed with
CloseProtocol(). This is required
+ to guarantee the state of ControllerHandle is not modified by this function.

EFI_DRIVER_BINDING_PROTOCOL instance.
+ @param[in] ControllerHandle The handle of the controller to test. This
handle

+ @param[in] RemainingDevicePath A pointer to the remaining portion of a
device path. This
+ parameter is ignored by device drivers, and is optional for
bus
+ drivers. For bus drivers, if this parameter is not NULL, then
+ the bus driver must determine if the bus controller
specified
+ by ControllerHandle and the child controller specified
+ by RemainingDevicePath are both supported by this
+ bus driver.
