Commit Message

  With mt7621 soc_dev_attr fixed to register the soc as a device,
kernel will experience an oops in soc_device_match_attr

This quirk test was introduced in the staging driver in
commit b483b4e4d3f6 ("staging: mt7621-pci: add quirks for 'E2' revision
using 'soc_device_attribute'"), and the staging driver was moved in
commit 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host
controller driver") for the 5.16 kernel

I am pretty sure I already gave my Acked-by in the previous version of
this patch. You should add tags when you submit new versiones. Anyway:
