[ Upstream commit a3ea410cac41b19a5490aad7fe6d9a9a772e646e ]
Josef reported that his old-and-good Plextor ConvertX M402U video converter spews lots of WARNINGs on the recent kernels, and it turned out that the device uses a bulk endpoint for interrupt handling just like 2250 board.
For fixing it, generalize the check with the proper verification of the endpoint instead of hard-coded board type check.
