   fbdev: omapfb: avoid stack overflow warning (2023-01-04 19:09:40 +0100)

----------------------------------------------------------------

- Prevent use-after-free in fbmem

       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.

Sure.

I'll send a new pull request where this patch is dropped.

Thanks!
