Hi,
with kernel 5.10.x and 5.12.x I'm getting a null pointer dereference
exception from the mcp251x driver when I resume from sleep (see trace
below).
As far as I can tell this was working fine with 5.4. As I currently don't
have the time to do further debugging/bisecting, for now I want to at least
report this here.
Maybe there is someone around who could already give a wild guess for what
might cause this just by looking at the trace/code!?
Does revert of c7299fea6769 ("spi: Fix spi device unregister flow") help?
This commit is so new, that it is neither in 5.10.x nor in 5.12.1. So it
can't be the reason.
