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: 19098934f9
"This patch is in upstream kernel, but it was backported to the old
staging driver in kernel 5.15."
