2011-12-12usb: gadget: renesas_usbhs: check device0 status when allocKuninori Morimoto1-14/+22
device0 was treated without checking in usbhsh_device_alloc(). but "udev->usbv" and "dev_set_drvdata()" will be overwritten if device0 was multi-allocated. This patch fixes this issue. Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2011-12-12usb: gadget: renesas_usbhs: cleanup complicated ureq alloc/freeKuninori Morimoto1-51/+56
DCP data/status stage needs ureq to usbhs_pkt_push(), but sometimes, there is no data stage. In that case, allocated ureq was not freed, Current ureq alloc/free pair were difficult to understand. This patch removed unnecessary/un-understandable ureq alloc from usbhsh_urb_enqueue(), and create simpler alloc/free pair.
