This is a note to let you know that I've just added the patch titled PCI: mt7621: Add sentinel to quirks table to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: pci-mt7621-add-sentinel-to-quirks-table.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 148f0633fdb43ebe2ad624b6f7c58dfaa371cd74 Author: John Thomson <git@xxxxxxxxxxxxxxxxxxxxxxxxxxx> Date: Tue Dec 6 06:46:45 2022 +1000 PCI: mt7621: Add sentinel to quirks table [ Upstream commit 19098934f910b4d47cb30251dd39ffa57bef9523 ] 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.
