3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
commit 8d1aad7485e653c2c5fd985b326096f680f7d918 upstream.
In commit f3ce4d5 ("usb: musb: core: call dma_controller_destroy() in the err path")
I erroneously assumed that the dma controller is not removed in the
error patch. This was wrong because it happens later via musb_free().
That means the original commit can be reverted because it is wrong or we
do this, so it is more obvious.
