   3 Subject: [PATCH] PCI: mt7621: Drop of_match_ptr() to avoid unused variable
   4
   5 We have stubs for most OF interfaces even when CONFIG_OF is not set, so we
   6 allow building of pcie-mt7621.c in that case for compile testing.
   7
   8 When CONFIG_OF is not set, "of_match_ptr(mt7621_pcie_ids)" compiles to
   9 NULL, which leaves mt7621_pcie_ids unused:
  10
  11   $ make W=1
  12   drivers/pci/controller/pcie-mt7621.c:549:34: warning: unused variable 'mt7621_pcie_ids' [-Wunused-const-variable]
  13
  14 Drop of_match_ptr() to avoid the unused variable warning.
