Message-Id: <18cec113071d0f471ba97dd34ece3a5256a6937b.1472502978.git.johnyoun@synopsys.com> Date: Mon, 29 Aug 2016 13:39:00 -0700 From: John Youn <johnyoun@...opsys.com> To: Stefan Wahren <stefan.wahren@...e.com> Cc: Robert Baldyga <r.baldyga@...sung.com> Subject: [PATCH 5/6] usb: dwc2: gadget: free TX FIFO after killing requests From: Robert Baldyga <r.baldyga@...sung.com> As kill_all_requests() potentially flushes TX FIFO, we should should free FIFO after calling it. Otherwise FIFO could stay unflushed properly.
