Subject: [PATCH AUTOSEL 5.15 2/8] ASoC: soc-pcm: fix hw->formats cleared by soc_pcm_hw_init() for dpcm
From: Shengjiu Wang <shengjiu.wang@....com>
[ Upstream commit 083a25b18d6ad9f1f540e629909aa3eaaaf01823 ]
The hw->formats may be set by snd_dmaengine_pcm_refine_runtime_hwparams()
in component's startup()/open(), but soc_pcm_hw_init() will init
hw->formats in dpcm_runtime_setup_fe() after component's startup()/open(),
which causes the valuable hw->formats to be cleared.
So need to store the hw->formats before initialization, then restore
it after initialization.
