In commit 38d5487db7f289be1d56ac7df704ee49ed3213b9, Keith explained:
This patch simply merges the two mode type bits together; that seems
reasonable to me, but perhaps only a subset of the bits should be
used? None of these can be user defined as they all come from
looking at just the hardware.
However, merging the bits means that a flag becomes sticky. It is not
possible, for example to update the mode type to remove the
DRM_MODE_TYPE_PREFERRED bit.
After a brief discussion with Dave Airlie on irc, it was agreed to
propose that change, instead of introducing another function to remove a
bit from exisiting modes type.
