v2:
   - Avoid mulitple return statements in amdgpu_dig_monitor_is_duallink
     function without affecting functionality
   - Fix following warnings: 
        WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
	WARNING: Missing a blank line after declarations

+                       amdgpu_encoder->active_device = amdgpu_encoder->devices & amdgpu_connector->devices;
