From 5984af1082f3b115082178ed88c47033d43b924d Mon Sep 17 00:00:00 2001 From: Pintu Agarwal Date: Wed, 15 Nov 2017 17:34:26 -0800 Subject: [PATCH] mm/cma.c: change pr_info to pr_err for cma_alloc fail log It was observed that under cma_alloc fail log, pr_info was used instead of pr_err. This will lead to problems 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.
