4. Quilt gave this output when I applied the patch to rebase it:

Applied patch platform/100-PCI-mt7621-Add-MediaTek-MT7621-PCIe-host-controller-.patch (forced; needs refresh)

Upon inspecting drivers/staging/mt7621-pci/pci-mt7621.c.rej, it seems that
the original patch wants to delete drivers/staging/mt7621-pci/pci-mt7621.c
but upstream's version was not an exact match.  I opted to delete that
file.

5. Suggestion by hauke: https://github.com/torvalds/linux/commit/19098934f910b4d47cb30251dd39ffa57bef9523
"This patch is in upstream kernel, but it was backported to the old
staging driver in kernel 5.15."
