Thanks Andy.
Hi Gerd:
I am a newbie, andy gave me some directions to submit the patch, eg: check
ioremap leak. At this time, I found that the bochs driver may have similar
problems, so I submitted this patch, then, Andy said the best is to switch
this driver to use pcim _ * () functions and drop tons of legacy code.
I think we might be able to fix this issue first, after that, drop tons
of legacy code by pcim_*() functions. Can you give me some suggestions?
thank you very much!
BR,
