#     module: remove never implemented MODULE_SUPPORTED_DEVICE
#     
#     MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
#     implemented. We can safely remove it, because the kernel has grown
#     to have many more reliable mechanisms to determine if device is
#     supported or not.
