Subject: [PATCH] ARM: pxa: ssp: remove unnessary free for devm_xxx
Date: Mon, 8 Jun 2015 14:19:06 +0800 [thread overview]
Message-ID: <1433744346-14095-1-git-send-email-firogm@gmail.com> (raw)
A Coccinelle warning.
It's not necessary to free memory allocated with devm_xxx
and using these free functions maybe lead to a double free that
will corrupt the resource subsys. So, I just remove them.
