Subject: usb: gadget: dummy_hcd: replace timeval with timespec64
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=04c4d8d4d556256ca8131dd780427e2fbfbd0270;p=deliverable%2Flinux.git

usb: gadget: dummy_hcd: replace timeval with timespec64

The millisecond of the last second will be normal if tv_sec is
overflowed. But for y2038 consistency and demonstration purpose,
and avoiding further risks, we need to remove 'timeval' in this
driver, to avoid similair problems.
