The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From a50ea34d6dd00a12c9cd29cf7b0fa72816bffbcb Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Tue, 2 Feb 2021 16:38:24 +0800 Subject: usb: xhci-mtk: break loop when find the endpoint to drop No need to check the following endpoints after finding the endpoint wanted to drop.
