Subject: [PATCH v2 03/12] da7210: fix a memory leak if failed to initialise da7210 audio codec
Date: Fri, 23 Jul 2010 05:53:45 +0000 [thread overview]
Message-ID: <1279864434-8010-4-git-send-email-axel.lin@gmail.com> (raw)
In-Reply-To: <1279864434-8010-1-git-send-email-axel.lin@gmail.com>
da7210 should be kfreed if da7210_init() return error.
This patch also fixes the error handing in the case of snd_soc_register_dai()
fail by adding snd_soc_unregister_codec() in error path.
