[PATCH] ASoC: don't call soc_cleanup_card_resources() at snd_soc_instantiate_card()

[PATCH] ASoC: don't call soc_cleanup_card_resources() at snd_soc_instantiate_card()

[Kuninori Morimoto]

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

commit adb76b5b9c47 ("ASoC: soc-core: remove legacy style dai_link")
removed legacy style dai_link from soc-core, and
commit 70fc53734e71 ("ASoC: core: move DAI pre-links initiation to
snd_soc_instantiate_card") moves soc_init_dai_link() timing.

Because of these, we don't need to call soc_cleanup_card_resources() if
soc_init_dai_link() was failed, otherwise, we will get Kernel crash.

Fixes: adb76b5b9c47 ("ASoC: soc-core: remove legacy style dai_link")
Fixes: 70fc53734e71 ("ASoC: core: move DAI pre-links initiation to snd_soc_instantiate_card")
