Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

/* Our private DDC functions
It complies somewhat with the corresponding VESA function
in arguments and return values.
Since this is probably called before the mode is changed,
we use our pre-detected pSiS-values instead of SiS_Pr as
regards chipset and video bridge type.
Arguments:
adaptnum: 0=CRT1(analog), 1=CRT2/LCD(digital), 2=CRT2/VGA2(analog)
CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
LCDA is CRT1, but DDC is read from CRT2 port.
DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
buffer: ptr to 256 data bytes which will be filled with read data.
Returns 0xFFFF if error, otherwise
if DDCdatatype > 0: Returns 0 if reading OK (included a correct checksum)
if DDCdatatype = 0: Returns supported DDC modes
