[PATCH v2 04/23] PCI: designware-plat: Prefer of_device_get_match_data()

From: Bjorn Helgaas
Date: Wed Dec 22 2021 - 20:11:24 EST


From: Fan Fei <ffclaire1224@xxxxxxxxx>

The designware-plat driver only needs the device data, not the whole struct
of_device_id. Use of_device_get_match_data() instead of of_match_device().
No functional change intended.
