Yicong Yang b8d976c7d4 hwtracing: hisi_ptt: Only add the supported devices to the filters list ... The PTT device can only support the devices on the same PCIe core, within BDF range [lower_bdf, upper_bdf]. It's not correct to assume the devices on the root bus are from the same PCIe core, there are cases that root ports from different PCIe core are sharing the same bus. So check when initializing the filters list.
