Subject: [PATCH] ASoC: atmel: disable error interrupt
Date: Wed, 04 Sep 2013 07:27:46 +0000 [thread overview]
Message-ID: <1378279666-19873-1-git-send-email-voice.shen@atmel.com> (raw)
As once the error interrupt is triggered, it can not be cleared.
So, disable it.
No side effect found while testing on sama5d3xek and at91sam9x5ek
boards.
