Subject: [PATCH 3.12 035/142] media: media-device: Remove duplicated memset() in media_enum_entities()

From: Salva Peiró <speiro@....upv.es>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit f8ca6ac00d2ba24c5557f08f81439cd3432f0802 upstream.

After the zeroing the whole struct struct media_entity_desc u_ent,
it is no longer necessary to memset(0) its u_ent.name field.
