From fa5034c667c224be48db31a0d043dba305e8e7a8 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Sat, 5 Nov 2011 18:42:01 -0300 Subject: [PATCH] [media] media: fix truncated entity specification When enumerating an entity, assign the entire entity specification instead of only the first two words. (This requires giving the specification union a name.) So far, no driver actually uses more than two words, but this will be needed for ALSA entities.
