drm: Make the per-driver file_operations struct const
From fdf1fdebaa00f81de18c227f32f8074c8b352d50 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan@linux.intel.com> Date: Sun, 30 Oct 2011 19:06:07 -0700 Subject: [PATCH] drm: Make the per-driver file_operations struct const The DRM layer keeps a copy of struct file_operations inside its big driver struct... which prevents it from being consistent and static. For consistency (and the general security objective of having such things static), it's desirable to get this fixed. This patch splits out the file_operations field to its own struct, which is then "static const", and just stick a pointer to this into the driver struct, making it more consistent with how the rest of the kernel does this.
