The commit caused bootup failure on QCN9274 hw2.0 platform. Incorrect hardcode DP irq offset overwrite the CE irq, which caused the driver to miss the mandatory bootup message from the firmware through the CE interrupt. This occurs because the CE count differs between platforms. The revert has no impact since the original change was based on an incorrect assumption.
