Subject: dm: usb: emul: Drop usb_emul_reset()
X-Git-Tag: v2017.11-rc1~2^2~15
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ad56e4b684a97565cdce15c28df1ccff9032d594;p=u-boot

dm: usb: emul: Drop usb_emul_reset()

With the root hub unbinding in usb_stop(), there is no need to do
a Sandbox-specific reset operation. usb_emul_reset() is no longer
used anywhere, drop it.
