Dan WilliamsandGreg Kroah-Hartman a6f5c84b41 cxl/hdm: Fail upon detecting 0-sized decoders
commit 7701c8bef4 upstream.

Decoders committed with 0-size lead to later crashes on shutdown as
__cxl_dpa_release() assumes a 'struct resource' has been established in
the in 'cxlds->dpa_res'. Just fail the driver load in this instance
since there are deeper problems with the enumeration or the setup when
this happens.
