Re: [PATCH v2] Revert "fbdev: Make fb_release() return -ENODEV if fbdev was unregistered"

[public]

Thanks for this patch. Do you think this can be backported to LTS 5.17.y and
5.15.y, which are still buggy? It's not a big deal for me but others might
profit.

Background:
The patch solves a regression from 5.17.1 to 5.17.2 or 5.15.32 and
5.15.33 I was about to report. On my Thinkpad T570, I got random "BUG", "Oops"
or even panics when during booting with efifb and plymouthd (and then sometimes
also problems when shutting down because). I had bisected the issue to commit
27599aacbaef. I could provide more info but I don't think it's necessary given
that either aafa025c76dcc7d1a8c8f0bdefcbe4eb480b2f6a or your better patch now
fixes the issue (I tested both, both work for me).

Best,
Tim Ruffing
