[PATCH 12/14] GPU-DRM-OMAP: Move a variable assignment in omap_gem_attach_pages()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 21 Sep 2016 17:42:28 +0200

Move one assignment for the local variable "npages" so that its setting
will only be performed after a call of the function "drm_gem_get_pages"
succeeded by this function.
