From 324e87b7e135c01725a9cef02cb8436f65e65f07 Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Fri, 19 Aug 2016 13:09:34 +0200 Subject: [PATCH] staging: most: aim-cdev: report error returned by alloc_chrdev_region This patch forwards the error code returned by function alloc_chrdev_region(). It is needed to stop the module from hiding the actual cause of failure.
