Subject: [PATCH 3.16 321/366] ARM: davinci: board-dm646x-evm: set VPIF
 capture card name

3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Sekhar Nori <nsekhar@...com>

commit bb7298a7e87cf3430eb62be8746e5d7a07ca9d7c upstream.

VPIF capture driver expects card name to be set since it
uses it without checking for NULL. The commit which
introduced VPIF display and capture support added card
name only for display, not for capture.

Set it in platform data to probe driver successfully.

While at it, also fix the display card name to something more
appropriate.

Fixes: 85609c1ccda6 ("DaVinci: DM646x - platform changes for vpif capture and display drivers")
