Today's linux-next has a bunch of issues, at least with my AX210 (0024) card. First I got a GPF in iwl_request_firmware(), cfg->fw_name_pre was invalid. After some digging into it I found that 6f60fb03c8e7 ("iwlwifi: move SnJ and So rules to the new tables") removed the entries for some cards. Obviously 5febcdef3090 and 9b15596c5006 weren't synced with some parallel development. After adding the entry for 0024 I now get the following lockdep warning. Isn't there any regression testing with lockdep enabled? Also warning "api flags index 2 larger than supported by driver" is still there, IIRC we talked about this weeks ago.
