Hmm, ok, I'm a bit confused here.
I though the omap_hdmi_audio device was a new thing, and thus it was ok
to add to omapdss. But now I see omap_hdmi_audio is already registered
in arch/arm/mach-omap2/devices.c, meaning the same platform device is
registered twice now. Well, with the exception of the device id, which
is -1 for the one from devices.c, and 0 for the one in omapdss.
Mark is right, this is not right. The kernel should work fine after each
patch, which means that sometimes a patch will touch multiple different
areas of kernel.
omapdss master branch is a stable branch, so I don't want to rebase it.
But I guess I can "reset" it by merging a mainline using some merge
strategy. I haven't done that before, but I guess it'll work.
Can you look at all the HDMI patches related to this hdmi-device change,
and rewrite them so that they'll keep the kernel working after each patch?
