[PATCH 3/8] powerpc/pseries/eeh: Export eeh_unfreeze_pe() and eeh_ops

From: Timothy Pearson
Date: Wed Jun 18 2025 - 00:22:49 EST


The PowerNV hotplug driver needs to be able to detect and clear any
frozen PE on the PHB after suprise removal of a downstream device.

Export the eeh_unfreeze_pe() and eeh_ops symbols to allow implementation
of this functionality in the php_nv module.
