Thank you for pointing this out and catching the potential issue.

I have verified this, and you are absolutely right. The issue stems from
the strcmp(name, manufacturers[i]->parts[j].name) evaluation within the
legacy probe path. Since 6.6.y lacks the null guard, passing a NULL .name
will result in a null pointer dereference in strcmp() and cause a kernel
oops during boot.

I will add the .name to the new flash entries and submit a v2 series.
