[PATCH] savagefb: Fix load failure of the Twister chipset
- The Twister chipsets are actually prosavages. Reclassify them as such and remove the S3_SAVAGE_TWISTER id. - Fix i2c code if fb_firmware_edid() returns NULL Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
