False positive inherit-non-class when inheriting a generic Protocol #9106
Description
Bug description
In the official Protocol PEP, inheriting directly from a protocol is ok: https://peps.python.org/pep-0544/#explicitly-declaring-implementation
However pylint 3 complains about inheriting from a generic protocol such as below:
class Channel(Protocol[T]):
"""A communication channel between nodes that can be closed"""
async def get(self) -> T:
"""Raises GeneratorExit when no more values are available"""
async def put(self, value: T):
...
async def close(self) -> None:
...
class DirectChannel(Channel[T]):
# etc..Configuration
