Subject: usb: dwc3: gadget: start Bulk endpoints more frequently
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ba62c09d5cc240e55eb39e92d88f1036bb1d9221;p=linux-beck.git

usb: dwc3: gadget: start Bulk endpoints more frequently

gadget driver queues a new request. This will make
sure we keep controller's queue busy for as long as
possible.
