vgacon: Set VGA struct resource types
[ Upstream commit c82084117f79bcae085e40da526253736a247120 ] Set the resource type when we reserve VGA-related I/O port resources. The resource code doesn't actually look at the type, so it inserts resources without a type in the tree correctly even without this change. But if we ever print a resource without a type, it looks like this: vga+ [??? 0x000003c0-0x000003df flags 0x0] Setting the type means it will be printed correctly as: vga+ [io 0x000003c0-0x000003df] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
