From b39599b7cb8f295205b04827ff82e3afec687cde Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 6 Mar 2013 16:56:48 -0600 Subject: [PATCH] remoteproc: fix the error check for idr_alloc The new idr_alloc interface returns the allocated id back on success, so fix the error path to check for negative values. This was missed out in the newer idr interface adoption patch, 15fc611 "remoteproc: convert to idr_alloc()".
