Hi Marex,
We backported this patch to ubuntu 4.15.0-generic kernel, and found this
patch introduced the rsi driver crashing when running system resume on
the Dell 300x IoT platform (100% rate). Below is the log, After seeing
this log, the rsi wifi can't work anymore, need to run 'rmmod
rsi_sdio;modprobe rsi_sdio" to make it work again.
So do you know what is missing apart from this patch or this patch is
not suitable for 4.15 kernel at all?
Thanks,
Hui.
