[PATCH] mbxfb: Add framebuffer driver for the Intel 2700G
Add frame buffer driver for the 2700G LCD controller present on CompuLab CM-X270 computer module. [adaplas] - Add more informative help text to Kconfig - Make DEBUG a Kconfig option as FB_MBX_DEBUG - Remove #include mbxdebug.c, this is frowned upon - Remove redundant casts - Arrange #include's alphabetically - Trivial whitespace Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
