hello,

I have sent the modified patch to the following mailboxes. THX

gregkh@linuxfoundation.org
linux-serial@vger.kernel.org
linux-kernel@vger.kernel.org

Thanks for the pointer. It is good to get some reviews from Arm
people in the first place, so we don't break Arm like this.

Anyway, for anyone who might be watching, here is the new patch,

https://lore.kernel.org/linux-serial/1628825490-18937-1-git-send-email-hptsfb@gmail.com/ (local)

Unfortunately, I saw Greg mentioned that it was not based on
tty-next, so not something I can apply easily on linux-next here
as well.

That is because the code in tty-next (and linux-next), looks to already
do exactly what you submitted, right?

So is this working now for everyone in linux-next?

AFAICS commit b0819465be8b in linux-next still results in
amba_device-specific code being called from sbsa_uart_startup() and
sbsa_uart_shutdown(), which is what blows up.

Ick,  ok, can someone send me a revert with this information in it
please?

thanks,

greg k-h
