drm: use noop_llseek
The drm device drivers currently allow seeking on the character device but never care about the actual file position. When we change the default llseek operation to be no_llseek, calling llseek on a drm device would return an error condition, which is an API change. Explicitly setting noop_llseek lets us keep the current API. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: David Airlie <airlied@linux.ie> Cc: dri-devel@lists.freedesktop.org
