Subject: PCI: Remove unused attr variable in pci_dma_configure
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=664204410afb3b0f538d176ad0c2713b04abd4b9;p=openwrt%2Fstaging%2Fblogic.git

PCI: Remove unused attr variable in pci_dma_configure

Clang warns:

drivers/pci/pci-driver.c:1603:21: error: unused variable 'attr'
[-Werror,-Wunused-variable]

Commit e5361ca29f2f ("ACPI / scan: Refactor _CCA enforcement") removed
attr's use and replaced it with its assigned value so it is no longer
needed.
