[PATCH v3 0/3] hw/usb/hcd-ehci: Fix Coverity CID 1685236 and check DMA errors

v1:
 1. Fix Fix Coverity CID 1685236
 
v2:
 1. Drops the dead NULL test and checks the actual accesses instead, and makes put_dwords() return void
    since no caller can act on a failed writeback.

v3:
 1. Make get_dwords() return bool

Jamin Lin (3):
  hw/usb/hcd-ehci: Check for DMA errors in get_dwords()/put_dwords()
  hw/usb/hcd-ehci: Make get_dwords() return bool
  hw/usb/hcd-ehci: Handle get_dwords() failures in async writeback
