4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Bartosz Markowski <bartosz.markowski@xxxxxxxxx> commit b08b5b53a1ed2bd7a883f8fd29232c8f03604671 upstream. Similarly to QCA6174, QCA9377 requires the CE5 configuration to be available for other feature. Use the ath10k_pci_override_ce_config() for it as well. This is required for TF2.0 firmware. Previous FW revisions were working fine without this patch.
