Broken builds

[Russell King - ARM Linux]

Looks like the DSS stuff has broken OMAP builds again during this
merge window:

drivers/video/omap2/dss/core.c:197: error: static declaration of 'dss_debugfs_create_file' follows non-static declaration
drivers/video/omap2/dss/dss.h:166: error: previous declaration of 'dss_debugfs_create_file' was here

Both the OMAP3 and OMAP4 builds break with these two errors.

Here's a patch for Tomi to fix this one.

I have a patch for this in my for-rc branch. It just missed the main
merge. I'll send this and a few other fixes today for the next rc.

Btw, it compiles if you have debugfs and DSS_DEBUG_SUPPORT enabled.
That's why I didn't notice it until too late.

Tomi, please have your patches sitting in linux next for at least a
week before they get merged. That usually shakes down bugs like these
before the merge window.

Note that tested simple bug fixes _should_ be upstreamed faster than
that where possible - such as this one.

I'm waiting for this to hit mainline before doing any further work on
OMAP.  That basically means I've been totally ignoring OMAP because of
this issue for the last week.

Okay. Perhaps I should have sent the patch directly to Linus, instead of
sending a pull request to fbdev maintainer. There's always a possibility
of delays with intermediate trees.

Then again, I don't see that it's such a big problem that I'd want to
skip the normal route for patches. Sure the bug is annoying, but one can
easily avoid the bug by just enabling CONFIG_DEBUG_FS and
CONFIG_OMAP2_DSS_DEBUG_SUPPORT.

I've now improved my testing process, and I hope things will go smoother
during the next merge window. Sorry about the mess.

 Tomi

So... where are we with this?  Apparantly not much further forward;
it seems to be in linux-next but still not in mainline, and mainline
continues to be broken.

The fixes have been pulled into fbdev tree, but it missed the -rc2.
Fbdev maintainer said "I merged this some days ago. Sorry that I didn't
realize that rc2 would be released early and hence didn't manage to get
it in."
