Johannes Berg 26f98b2d97 iwlwifi: pcie: make cfg vs. trans_cfg more robust ... [ Upstream commit 48a5494d6a ] If we (for example) have a trans_cfg entry in the PCI IDs table, but then don't find a full cfg entry for it in the info table, we fall through to the code that treats the PCI ID table entry as a full cfg entry. This obviously causes crashes later, e.g. when trying to build the firmware name string. Avoid such crashes by using the low bit of the pointer as a tag for trans_cfg entries (automatically using a macro that checks the type when assigning) and then checking that before trying to use the data as a full entry - if it's just a partial entry at that point, fail. Since we're adding some macro magic, also check that the type is in fact either struct iwl_cfg_trans_params or struct iwl_cfg, failing compilation ("initializer element is not constant") if it isn't.
