3.2.81-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> commit 2fd0f46cb1b82587c7ae4a616d69057fb9bd0af7 upstream. In usecases where force_port_map is used saved_port_map is never set, resulting in not programming the PORTS_IMPL register as part of initial config. This patch fixes this by setting it to port_map even in case where force_port_map is used, making it more inline with other parts of the code.
