[PATCH] drivers/video/: possible cleanups
This patch contains the possible cleanups including the following: - every file should #include the headers containing the prototypes for it's global functions - make needlessly global functions static - kyro/STG4000Interface.h: #include video/kyro.h and linux/pci.h instead of a manual "struct pci_dev" - i810_main.{c,h}: prototypes for static functions belong to the C file Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: "Antonino A. Daplas" <adaplas@hotpop.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

68 * So for chipsets with 64 MiB Aperture sizes, 32 MiB for v_offset is okay, allowing up to
69 * 15 + 1 MiB of Framebuffer memory. For 32 MiB Aperture sizes, a v_offset of 8 MiB should
70 * work, allowing 7 + 1 MiB of Framebuffer memory.
71 * Note, the size of the hole may change depending on how much memory you allocate to X,
72 * and how the memory is split up between these surfaces.
73 *
74 * Note: Anytime the DepthBuffer or FrontBuffer is overlapped, X would still run but with
75 * DRI disabled. But if the Frontbuffer is overlapped, X will fail to load.
76 *
77 * Experiment with v_offset to find out which works best for you.
