I don't know what is the future of those modifications but maybe instead
of fully reverting them, maybe you could perform calls to
- pcie_clkpm_override_default_link_state() and
- pcie_aspm_override_default_link_state()
only if a new Kconfig symbol is enabled.
Of course this symbols will be disabled by default but if you want some
people to test behavior, it could be interesting to have the code
available in the kernel.
I don't know, this was just an idea.
Of course, reverting the patch is simpler than adding this new Kconfig
symbol.
Best regards,
Hervé
