From ff377ae47de5c395ec47baabcde0f3011e71ae70 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Tue, 25 Oct 2016 13:54:00 +0300 Subject: usb: dwc3: gadget: always kick if num_pending_sgs > 0 When we get a half-way processed request, we should make sure to try to prepare further TRBs for it or for any possibly queued up request held in our pending_list. This will make sure our controller is kept busy for as long as possible.
