[alsa-devel] [PATCH 1/9] ASoC: Intel: Skylake: remove BE startup dai ops

[Vinod Koul]

From: Jeeja KP <jeeja.kp at intel.com>

We have moved the runtime calls from BE startup to HW params, this helps to
optimize the unnecessary wakes due to users opening and closing device
As a result startup is empty so remove that
