fbdev: omapfb: avoid stack overflow warning (2023-01-04 19:09:40 +0100)
----------------------------------------------------------------
fbdev updates for kernel 6.2-rc3:
- Fix Matrox G200eW initialization failure
- Fix build failure of offb driver when built as module
- Optimize stack usage in omapfb
- Prevent use-after-free in fbmem
----------------------------------------------------------------

fbdev: omapfb: avoid stack overflow warning
Hang Zhang (1):
fbdev: fbmem: prevent potential use-after-free issues with console_lock()
I looked at this, and even by fbdev locking standards this makes
absolutely no sense to me. I think this should be dropped before we've
reached some sort of conclusion on what is going on, or whether this
is just pure static checker conjecture without fully understanding how
this is supposed to work really.
Just to close this: Turned out to be some kind of static checker dud
(and unfortunately the commit message didn't even explain that it was
found through some undisclosed static checker, I asked the submitter
to rectify this going forward since they'll likely submit more stuff
like this).

Thank you, Daniel!
