[ Upstream commit 572b7cf08403b6c67dfe0dc3e0f2efb42443254f ]
If do_cpt_init() fails, a previous dma_alloc_coherent() call needs to be
undone.
Add the needed dma_free_coherent() before returning.

[ Upstream commit 53d91ca76b6c426c546542a44c78507b42008c9e ]
The while loop breaks in the first run because of incorrect
if condition. It also causes the statements after the if to
appear dead.
Fix this by changing the condition from if(timeout--) to
if(!timeout--).
This bug was reported by Coverity Scan.
Report:
CID 1600859: (#1 of 1): Logically dead code (DEADCODE)
