It does actually,
drivers/pci/controller/pcie-rcar-host.c: In function ‘rcar_pcie_hw_enable’:
drivers/pci/controller/pcie-rcar-host.c:357:34: warning: declaration
of ‘res’ shadows a previous local [-Wshadow]
357 | struct resource *res = win->res;

So, I'll respin it with the fixes tag added.

Cheers,
Prabhakar
