All issues have been introduced by the same commit, 8765c5ba1949 ("ACPI / scan: Rework modalias creation when "compatible" is present") The first 2 patches fixe some issues related to string truncation checks and to computation of the available space in the output buffer. The 2 others are just some clean-ups.
