This change is breaking a PCI test that we are running on Tegra124
Jetson TK1. The test is parsing the various PCI devices by running
'lspci -vvv' and for one device I am seeing a NULL pointer
dereference crash. Reverting this change or just adding the line
'dev->vpd.len = PCI_VPD_MAX_SIZE;' back fixes the problem.

I have taken a quick look but have not found why this is failing
so far. Let me know if you have any thoughts.

There's a known issue with this change, the fix has just been applied to
linux-next. Can you please re-test with linux-next from today?

Thanks. Looking at yesterday's -next, I do see that it is now working again.

Cheers
Jon
