Probe deferral is an expected error condition that will usually be
recovered from. Print such error messages at debug level to make them
available for diagnostic purposes when building with debugging enabled
and hide them otherwise to not spam the kernel log with them.

Hi Thierry,
what tree/branch is it based on ? I assume it may depend on some
patches queued in one of my branches so please let me know and
I will apply accordingly.
Thanks,
Lorenzo

Hi Lorenzo,
This should apply on top of commit 5b645b7fade9 ("PCI: tegra: Add
support for PCIe endpoint mode in Tegra194") which is currently in
linux-next.
Looking at your "pci" tree, that commit seems to be in a branch
called pci/endpoint, though the equivalent commit there has a slightly
different SHA:
f4746b0ccef9 ("PCI: tegra: Add support for PCIe endpoint mode in Tegra194")
git range-diff shows that the only difference is that in the patch in
linux-next there are a couple of additional exported symbols that are
not in your pci/endpoint branch. That shouldn't be relevant, though,
since this patch touches another area of the code, so applying this to
your pci/endpoint branch should work.
