Subject: [PATCH 12/17] usb: xhci-mtk: rebuild the way to get bandwidth domain
Date: Fri, 5 Mar 2021 17:02:50 +0800	[thread overview]
Message-ID: <1614934975-15188-12-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1614934975-15188-1-git-send-email-chunfeng.yun@mediatek.com>

Rebuild the function get_bw_index(), get the bandwidth domain
directly instead its index of domain array.
