Subject: usb: ci_udc: call udc_disconnect() from ci_pullup()
X-Git-Tag: v2014.07-rc4~111^2~5
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=43a8f25b6ca77894ddfd46c2b1196c7bd487561f;p=u-boot

usb: ci_udc: call udc_disconnect() from ci_pullup()

ci_pullup()'s !is_on path contains a cut/paste copy of udc_disconnect().
Remove the duplication by simply calling udc_disconnect() instead.
