Subject: PCI: layerscape: Move generic init functions earlier in file
X-Git-Tag: v4.14-rc1~87^2~22^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ba95a82e31490b2415e9fe967c6997f5dac8fe31;p=platform%2Fkernel%2Flinux-rpi.git

PCI: layerscape: Move generic init functions earlier in file

We will use the generic ls_pcie_link_up() and ls_pcie_host_init() from
device-specific routines.  Move the generic functions earlier in the file
so we won't need forward declarations.  This is strictly a code move with
no functional change intended.
