Subject: [PATCH] OMAP:DSS2:OMAPFB: Fix probe error path

Hi Tomi,

Is this change ok instead of having sysfs entry removal in omapfb_free_resources() ?
Hope this change makes probe look more of a remove mirror.

Regards
Afzal

Move sysfs entry creation to omapfb_probe() from omapfb_create_framebuffers().
This will make sure that sysfs entry is not left behind in case of unsuccessful
probe due to failure in enabling fb0 of omapfb_create_framebuffers().

Yes, I think this version is ok. Thanks!
