linux-next: build warning after merge of the pci tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the pci tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/pci/controller/dwc/pci-dra7xx.c: In function 'dra7xx_pcie_establish_link':
drivers/pci/controller/dwc/pci-dra7xx.c:142:6: warning: unused variable 'exp_cap_off' [-Wunused-variable]
  142 |  u32 exp_cap_off = dw_pcie_find_capability(pci, PCI_CAP_ID_EXP);
      |      ^~~~~~~~~~~

Introduced by commit

  3af45d34d30c ("PCI: dwc: Centralize link gen setting")
