From: Stanislaw Gruszka Date: Thu, 21 Mar 2019 15:25:31 +0000 (+0100) Subject: mt76usb: move mt76u_buf->done to queue entry X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=279ade99ed8f3bd2d2d52ab980161627402c705f;p=openwrt%2Fstaging%2Fblogic.git mt76usb: move mt76u_buf->done to queue entry 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.
