[PATCH v2 0/2] hw/usb/hcd-ehci: Fix Coverity CID 1685236 and check DMA errors

Posted by Jamin Lin 1 month, 1 week ago

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.

Jamin Lin (2):
  hw/usb/hcd-ehci: Handle get_dwords() failures in async writeback
  hw/usb/hcd-ehci: Check for DMA errors in get_dwords()/put_dwords()
