From e8e55dbe08960b714e5ce0148926ee17331ce4d5 Mon Sep 17 00:00:00 2001 From: Keyon Jie Date: Tue, 30 Apr 2019 18:09:29 -0500 Subject: [PATCH] ASoC: SOF: Intel: hda-stream: store stream capabilities Add stream_max into struct sof_intel_hda_dev to store the total hda stream number that the platform can support, and initialize it at stream_init. This can be used later e.g. for stream bitmask.
