6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <[email protected]>
commit 6f719373b943a955fee6fc2012aed207b65e2854 upstream.
Blank the display by disabling sync pulses with VGACR17<7>. Unblank
by reenabling them. This VGA setting should be supported by all Aspeed
hardware.
This patch breaks VGA output on my machine. I have already reported this
regression against mainline 6.18-rc2, see here:
https://lore.kernel.org/all/[email protected]/
When I revert this patch from 6.12.55-rc1, the issue goes away, just as in mainline. I'm still going to test 6.17.5-rc1
too and report back, but I guess it will be just the same.
Beste Grüße,
Peter Schneider
