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")
