From: Laurent Pinchart Date: Sun, 7 Mar 2010 18:04:59 +0000 (-0300) Subject: [media] media: Entity use count X-Git-Tag: v2.6.39-rc1~86^2~180 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=503c3d829eaf48837dd5bff5d97ad66369bb955a;p=pandora-kernel.git [media] media: Entity use count Due to the wide differences between drivers regarding power management needs, the media controller does not implement power management. However, the media_entity structure includes a use_count field that media drivers can use to track the number of users of every entity for power management needs. The use_count field is owned by media drivers and must not be touched by entity drivers. Access to the field must be protected by the media device graph_mutex lock.
