Analyze and fix the following issue in the Linux kernel code: firewire: core: align driver match with modalias
Problem Details: The driver match strategy was: - Match vendor/model/specifier/version of the unit directory. - If that was a miss, match vendor from the root directory and model/specifier/version of the unit directory. This was inconsistent with how the modalias string was constructed until recently (take ven...
