That means the struct member fwblks and the whole of detect_partition_feature() are unneeded. The comment block implies this function is only for Intel platforms. I found drivers/staging/spectra used to exist, but it was deleted by commit be7f39c5ecf5 ("Staging: delete spectra driver") 5 years ago. So, I guess nobody would need this function any more.
