From: Sergio Paracuellos Date: Mon, 24 Jan 2022 12:30:02 +0100 Subject: [PATCH] PCI: mt7621: Drop of_match_ptr() to avoid unused variable We have stubs for most OF interfaces even when CONFIG_OF is not set, so we allow building of pcie-mt7621.c in that case for compile testing. When CONFIG_OF is not set, "of_match_ptr(mt7621_pcie_ids)" compiles to NULL, which leaves mt7621_pcie_ids unused: $ make W=1 drivers/pci/controller/pcie-mt7621.c:549:34: warning: unused variable 'mt7621_pcie_ids' [-Wunused-const-variable] Drop of_match_ptr() to avoid the unused variable warning.
