Subject: x86: pci-swiotlb.c swiotlb_dma_ops should be static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ff6c6fed3a8ab9b0a7b02574e095e905e89421d9;p=linux.git

x86: pci-swiotlb.c swiotlb_dma_ops should be static

Impact: reduce kernel size a bit, address sparse warning

Addresses the problem pointed out by this sparse warning:

  arch/x86/kernel/pci-swiotlb.c:53:20: warning: symbol 'swiotlb_dma_ops' was not declared. Should it be static?

For x86: swiotlb_dma_ops can be static, because it's not used outside
of pci-swiotlb.c
