Hi,
This series unregister AT notifiers in removing various AT modem drivers when modem goes
to offline mode. Please review them.
We should fix other modem drivers other than atmodem as well. I will send seperate patches
for review.
To Emmanuel, could you try these patches to see wheter it fixes your problems? Thanks.
Regards,
Zhenhua

This series unregister AT notifiers in removing various AT modem drivers when modem goes

We should fix other modem drivers other than atmodem as well. I will send seperate
patches for review.
To Emmanuel, could you try these patches to see wheter it fixes your problems? Thanks.
Regards,
Zhenhua
Your patches are fine, however there is an alternative we'd like to
explore first that might turn out to be better. It does require some
surgery to GAtChat...

Hi Zhenhua,
This series unregister AT notifiers in removing various AT modem
drivers when modem goes to offline mode. Please review them.
just a heads up here that Denis and I talked about this. And we are
going to fix this inside GAtChat in the background for you. Trying to
fix this single handed in every atom driver is wrong.
This approach creates too much of a maintenance burden. And additional
code complexity and memory footprint doing it this way. So we have to
tackle it in a central place. And that is GAtChat.

Thanks for update. Yes. The fix by Denis looks smart and make sense to
me. By using fa?ade pattern, we don't require user to track
register/unregister of AT notifers any more.

Marcel
