[ 10.369177] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available
The broadcom driver supports loading a board/implementation-specific (not chipset-specific) tuning firmware (clm_blob) but very few boards have them and thus there is no blob to load in our image and the driver reports this. It should really be a warning not an error, but ISTR the driver uses the generic kernel firmware loading helpers so it's not possible to alter how that's reported without impacting the reporting of all kernel firmware loading which would not be desirable. In short, it's harmless. You might need to configure the wireless regdomain in the LE settings add-on for all channels to be available.
