Hi All,
I tried to run the application I got the following compilation error message
v4l2_drm
In file included from v4l2_drm.c:16:0:
/usr/include/xf86drm.h:40:17: fatal error: drm.h: No such file or directory
compilation terminated.
make: *** [v4l2_drm] Error 1
I am trying to use this in the USB and intel graphics driver (emgd or i915)
Please help me in this regard
Thanks,

From: Chris Wilson <chris at chris-wilson.co.uk>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 46eeb2c144956e88197439b5ee5cf221a91b0a81 upstream.
If we fail to remove a conflicting fb driver, we need to abort the loading of the second driver to avoid likely kernel panics.
