[PATCH -next] PCI: dwc: Remove set but not used variable
From: Liu Shixin <hidden>
Date: 2020-09-17 06:55:48
Also in:
linux-omap, linux-pci, lkml
Subsystem:
pci driver for ti dra7xx/j721e, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers:
Vignesh Raghavendra, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds
Fixes gcc '-Wunused-but-set-variable' 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]
After 3af45d34d30c ("PCI: dwc: Centralize link gen setting"), variable 'exp_cap_off'
is never used. Remove it to avoid build warning.
