Can the number start from 0 or is it expected to start from 1? It might
be useful to mention that if there is a constraint.

The driver currently doesn't do any enforcement on if the input starts at 0 / 1. If user writes 0 and if
the corresponding file it looks for (ff-mm-ss-00.<test_type>) is present, it would load it otherwise it would
return error-code ENOENT (returned by request_firmware_direct())
