From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 10 Aug 2017 00:07:00 +0000 Subject: [PATCH] ASoC: rsnd: call free_irq() both DMA/PIO mode

commit 701172dca15b ("ASoC: rsnd: don't use devm_request_irq() for SSI") exchanged devm_request_irq() to request_irq() for SSI, because SSI will fallback into PIO mode if DMA doesn't work. But, because of it, PIO mode needed to call free_irq() when removing, not only DMA mode. This patch call free_irq() both PIO/DMA. Otherwise, rsnd IRQ handler will be increased if user tried many unbind/bind.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 10 Aug 2017 00:07:38 +0000 Subject: [PATCH] ASoC: rsnd: call request_irq/free_irq once in MIX case

Each module's dai callback function availability is controlled by mod->status. For example "always called", "call once". In .probe/.remove case, it needs to be called always, because .probe will call xxx_attach() function on .probe, especially if platform is using MIXer. For example, below case, MIX0/DVC0/SSI0 needs to be called twice.

playback = <&src0 &ctu02 &mix0 &dvc0 &ssi0>; playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;

But in this case, SSI0 will call request_irq() twice. This patch add new RSND_SSI_PROBED flag and control it
