Subject: [PATCH] PCI: mt7621: Add sentinel to quirks table
Current driver is missing a sentinel in the struct soc_device_attribute
array, which causes an oops when assessed by the
soc_device_match(mt7621_pcie_quirks_match) call.
This was only exposed once the CONFIG_SOC_MT7621 mt7621 soc_dev_attr
was fixed to register the SOC as a device, in:
commit 7c18b64bba3b ("mips: ralink: mt7621: do not use kzalloc too early")
Fix it by adding the required sentinel.
