Subject: [PATCH net-next 0/3] enic: Check for DMA mapping error
Date: Wed, 24 Dec 2014 15:59:35 +0530	[thread overview]
Message-ID: <1419416978-1008-1-git-send-email-_govind@gmx.com> (raw)

After dma mapping the buffers, enic does not call dma_mapping_error() to check
if mapping is successful.

This series fixes the issue by checking return value of pci_dma_mapping_error()
after pci_map_single().

This is reported by redhat here
https://bugzilla.redhat.com/show_bug.cgi?id=1145016

  enic: make vnic_wq_buf doubly linked
  enic: check dma_mapping_error
  enic: add stats for dma mapping error
