[PATCH 06/12] mt76usb: move mt76u_buf->done to queue entry

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

 



mt76_queue_entry has alreay one bool variable, adding new one will
not increase it's size. Removing ->done filed from mt76u_buf will
allow to use urb directly in mt76usb code.
