PCI: Move pci_[get|set]_resource_alignment_param() into their callers
Both the functions pci_get_resource_alignment_param() and pci_set_resource_alignment_param() are now only called in one place: resource_alignment_show() and resource_alignment_store() respectively. There is no value in this extra set of functions so move both into their callers respectively. [bhelgaas: fold in "GFP_KERNEL while atomic" fix from Christoph Hellwig <hch@infradead.org> https://lore.kernel.org/r/20190902075006.GB754@infradead.org] Link: https://lore.kernel.org/r/20190822161013.5481-3-logang@deltatee.com Signed-off-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
