While fixing that, I also found & fixed a couple of other corner cases. This fixes booting with a pbbuttons version that scans the i2c bus for an LMU controller among others. Tested on a dual G5 with thermal control (which has heavy i2c activity) with no problem so far. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
