[PATCH v6 2/3] USB: Also check for ->match

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We only ever used the ID table matching before, but we should probably
also support an open-coded match function.

Fixes: 88b7381a939de ("USB: Select better matching USB drivers when available")
