a=openpgp; fpr=C668AEC3C3188E4C611465E7488550E901166008 All EP specific resources are enabled during PERST# deassert. As a counter operation, all resources should be disabled during PERST# assert. There is no point in skipping that if the link was not enabled. This will also result in enablement of the resources twice if PERST# got deasserted again. So remove the check from qcom_pcie_perst_assert() and disable all the resources unconditionally.
