Another thing on letux3704:
hdq woes:
rmmod omap_hdq ; modprobe omap_hdq causes a lot of mess[1]:
enabling serial runtime auto-suspend confuses omap_hdq. I do not get
values for current_now then.
Background: Probably serial devices were the last user of many things in
the soc (I did not load many modules), so re-requesting them by e.g.
omap_hdq has to be done properly.
Maybe that is the reason. I have not checked those things earlier, but
there were some changes there, so I experimented a bit.
