It was observed that under cma_alloc fail log, pr_info was used instead of pr_err. This will lead to problem if printk debug level is set to below 7. In this case the cma_alloc failure log will not be captured in the log and it will be difficult to debug.
Simply replace the pr_info with pr_err to capture failure log.
