Re: [PATCH] PCI: Add D3cold reset quirk for devices with broken/missing FLR

Thank you for your feedback and help

I tested quirk_no_flr() and it works perfectly for mt7925e. The related                                                                                                                                            
mt7922e device was already in that list so this was expected.

However, for the Qualcomm devices, that solution doesn't work and they
need a different approach.

So, I will submit two independent patches for v2: one for mt7925e following
your suggestion with quirk_no_flr(), and another for Qualcomm devices with a
different proposal trying to follow the same idea.
