From dc880abef75e7c62c9048171f5112500f36a9244 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 6 Jul 2010 18:54:47 +0200 Subject: [PATCH] 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.
