| | I find that this patch causes resume not to work, reproducibly, on my
| | GTA02.  That is to say:  I was trying to build a kernel from the tip of
| | the 'stable' branch and ran into  problems (unresponsive black screen
| | when trying to resume via the power button). I did a 'git bisect' and
| | isolated it to this commit, and reverting this commit (only) caused the
| | problem to go away for me.
| |
| | Is it possible that "dev->resume()" is not properly initialised somehow?
| | As far as I can see, this patch isn't meant to be anything more than a
| | tidy-up.  I'd love to have a go at tracking this down myself, but my
| | weekend reading on Linux Kernel Development is still in the post from
| | Amazon...
|
| Thanks for the effort isolating it, Mike too, I will look at it
| thismorning.

Yes the trouble is coming from dev->dev.driver being a struct
device_driver which has a (*resume) composed in it, but in fact the
Glamo's resume is defined in a separate struct platform_driver elsewhere
which has the real (*resume) we want in it.  So it looks really good to
the eye but is wrong.

This code and almost all or all of the resume_dependency stuff is gone
in the device tree changes for 2.6.26, so rather than try to figure out
how to derive the correct pointer I will revert this part of the patch.
