Subject: [PATCH] ASoC: rt5663: Change the dev getting function in rt5663_irq
Date: Mon, 25 Sep 2017 11:11:05 +0800 [thread overview]
Message-ID: <1506309065-25802-1-git-send-email-oder_chiou@realtek.com> (raw)
In the irq handler "rt5663_irq", while the codec is not initialized,
rt5663->codec will be null, and it will cause the kernel panic in the debug
print enabled.
