Subject: [PATCH] usb: musb: remove extra check in musb_gadget_vbus_draw

The checks for musb->xceiv and musb->xceiv->set_power duplicate those in usb_phy_set_power(), so there is no need of them. Moreover, not calling usb_phy_set_power() results in usb_phy_set_charger_current() not being called, so current USB config max current is not propagated through USB charger framework and charger drivers may try to draw more current than allowed or possible.

Fix that by removing those extra checks and calling usb_phy_set_power() directly.

Tested on Motorola Droid4 and Nokia N900
