[ 115/221] ext4: release buffer in failed path in dx_probe()

[Greg Kroah-Hartman]

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guo Chao <yan@xxxxxxxxxxxxxxxxxx>

commit 0ecaef0644973e9006fdbc6974301047aaff9bc6 upstream.

If checksum fails, we should also release the buffer
read from previous iteration.
