Subject: [PATCH AUTOSEL 5.15 08/28] ASoC: rsnd: care default case on rsnd_ssiu_busif_err_irq_ctrl()

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

[ Upstream commit ef30911d3c39fd57884c348c29b9cbff88def155 ]

Before, ssiu.c didn't care SSI5-8, thus,
commit b1384d4c95088d0 ("ASoC: rsnd: care default case on
rsnd_ssiu_busif_err_status_clear()") cares it for status clear.

But we should care it for error irq handling, too.
This patch cares it.
