Subject[PATCH 4.9 89/92] ASoC: rsnd: avoid duplicate free_irq()
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

commit e0936c3471a8411a5df327641fa3ffe12a2fb07b upstream.

commit 1f8754d4daea5f ("ASoC: rsnd: don't call free_irq() on
Parent SSI") fixed Parent SSI duplicate free_irq().
But on Renesas Sound, not only Parent SSI but also Multi SSI
have same issue.
This patch avoid duplicate free_irq() if it was not pure SSI.

Fixes: 1f8754d4daea5f ("ASoC: rsnd: don't call free_irq() on Parent SSI")
