Subject: [PATCH v2 01/18] usb: xhci-mtk: remove or operator for setting schedule parameters
Date: Mon, 8 Mar 2021 10:51:50 +0800 [thread overview]
Message-ID: <d287899e6beb2fc1bfb8900c75a872f628ecde55.1615170625.git.chunfeng.yun@mediatek.com> (raw)
Side effect may happen if use or operator to set schedule parameters
when the parameters are already set before. Set them directly due to
other bits are reserved.
Fixes: 54f6a8af3722 ("usb: xhci-mtk: skip dropping bandwidth of unchecked endpoints")
