Subject: [PATCH 06/12] mt76usb: move mt76u_buf->done to queue entry
Date:   Thu, 21 Mar 2019 16:25:31 +0100
Message-Id: <20190321152537.19105-7-sgruszka@redhat.com>
In-Reply-To: <20190321152537.19105-1-sgruszka@redhat.com>

Precedence: bulk

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.
