From d723818e7c8f20af0a665f5b0c2eda909e069ffa Mon Sep 17 00:00:00 2001 From: Felipe Contreras Date: Fri, 5 Nov 2010 17:01:48 +0000 Subject: [PATCH] staging: tidspbridge: fix mgr_enum_node_info The current code was always returning a non-zero status value to userspace applications when this ioctl was called. The error code was ENODATA, which isn't actually an error, it's always returned by dcd_enumerate_object() when it hits the end of list.
