Message-id: <1451319928-21250-6-git-send-email-r.baldyga@samsung.com> Date: Mon, 28 Dec 2015 17:25:28 +0100 From: Robert Baldyga <r.baldyga@...sung.com> To: balbi@...com, johnyoun@...opsys.com Cc: gregkh@...uxfoundation.org, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, m.szyprowski@...sung.com, b.zolnierkie@...sung.com, Robert Baldyga <r.baldyga@...sung.com> Subject: [PATCH 5/5] usb: dwc2: gadget: free TX FIFO after killing requests As kill_all_requests() potentially flushes TX FIFO, we should should free FIFO after calling it. Otherwise FIFO could stay unflushed properly.
