| Series | [v2] usb: musb: remove extra check in musb_gadget_vbus_draw | expand |
diff --git a/drivers/usb/musb/musb_gadget.c b/drivers/usb/musb/musb_gadget.c index 6cb9514..31c4432 100644 --- a/drivers/usb/musb/musb_gadget.c +++ b/drivers/usb/musb/musb_gadget.c @@ -1630,8 +1630,6 @@ static int musb_gadget_vbus_draw(struct usb_gadget *gadget, unsigned mA) { struct musb *musb = gadget_to_musb(gadget); - if (!musb->xceiv || !musb->xceiv->set_power) - return -EOPNOTSUPP; return usb_phy_set_power(musb->xceiv, mA); }
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.
