However, the patch version should really be tracked as well for the same reasons. The KMD can work without the change but if the effort has been taken to release a new firmware with the change then there must be a valid reason for doing so - important bug fix, security fix, etc. And in that case it would be good to alert the user if they are missing out on that new fix. v2: Use correct patch version number and drop redunant debug print (review by Daniele / CI results).

Which is unnecessary. So pull it out into a separate function that is only called once per blob type at init time. Also, drop the CONFIG_SELFTEST requirement and make errors terminal. It was mentioned that potential issues with backports would not be caught by regular pre-merge CI as that only occurs on tip not stable branches. Making the validation unconditional and failing driver load on detecting of a problem ensures that such backports will also be validated correctly. v2: Change to unconditionally fail module load on a validation error (review feedback/discussion with Daniele).

Duplicate entries are a bug anyway and so should never happen. Ensure they don't by tweaking the table validation code to reject duplicates. For full m/m/p files, that can be done by simply tweaking the patch level check to reject matching values. For reduced version entries, the filename itself must be compared.
