Hi Lukas,

I was wondering - is this fix connected to an issue filled in Bugzilla
or does it fix a known commit that introduced this problem?  Basically,
I am trying to see whether a "Fixes:" would be in order.

The fix is for a driver which has been removed from the tree (for now),
including in stable kernels.  The fix will prevent an issue that will
occur once the driver is re-introduced (once we've found a way to
overcome the issues that led to its removal).  A Fixes tag is thus
uncalled for.

Thank you for adding more details.  Much appreciated.

Krzysztof


I made the patch because it was causing the config space for a downstream port to not get restored when a DPC event occurred, and all the NVMe drives under it disappeared.  I found that myself, though--I'm not aware of anyone else reporting the issue.

Any chance this might get accepted? I'm not sure if it just got forgotten, or if there's a problem with it. Thanks! --Stuart
