The radeonfb code for DDC probing (like it's X.org counterpart) uses to leave the DDC clock & data lines asserted after the probing is complete. This causes problems with some Apple monitors like the new Cinema HD 23", who will turn themselves off when that happens. This fixes it.
Fix is correct, but comment is not ;) After the loop SCL and SDA are left low. Pulling them high puts the I2C bus in the stop condition.
