From fd9a5ca4df2ce459787db0249ac6b4896766e9c5 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 1 Feb 2021 21:47:20 +0900 Subject: usb: renesas_usbhs: Clear pipe running flag in usbhs_pkt_pop() commit 9917f0e3cdba7b9f1a23f70e3f70b1a106be54a8 upstream Should clear the pipe running flag in usbhs_pkt_pop(). Otherwise, we cannot use this pipe after dequeue was called while the pipe was running.
