Hi:

It has been a month since I submitted this patch. I'm wondering is it
still valid and wether it will be applied? 

A recent commit targeting at the same problem (commit 1a47de6 various:
fix pci_set_dma_mask return value checking) has been applied. But my
commit, which I reported and submitted earlier, hasn't been applied. I'd
like to know if there's anything wrong with it? 

Thank you!
