[alsa-devel] [PATCH 2/6] ASoC: sh: discontinue support of sh7760-ac97 driver

[Kuninori Morimoto]

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

In upstream kernel, no one is using SND_SH7760_AC97.
This patch discontinue support of sh7760-ac97 driver to reducing
maintenance cost. Thank you and good bye sh7760-ac97 driver.
