#     powerpc/kexec: Fix build failure from uninitialised variable
#     
#     clang 14 won't build because ret is uninitialised and can be returned if
#     both prop and fdtprop are NULL.  Drop the ret variable and return an
#     error in that failure case.
#     
#     Fixes: b1fc44eaa9ba ("pseries/iommu/ddw: Fix kdump to work in absence of ibm,dma-window")
