Subject: [PATCH 02/20] media: exynos4-is: media-dev.c: use PTR_ERR_OR_ZERO

From: "Daniel W. S. Almeida" <dwlsalmeida@...il.com>

Fixes the following coccinelle report:

drivers/media/platform/exynos4-is/media-dev.c:1273:1-3:
WARNING: PTR_ERR_OR_ZERO can be used

By using PTR_ERR_OR_ZERO in place of the existing logic.

Found using - Coccinelle (http://coccinelle.lip6.fr)
