Is this an unreported bug? or it has been reported and the solution is

CONFIG_PREEMPTION is enabled.

ppp_cp_event is called directly or indirectly by ppp_rx with "ppp->lock"
held. It may call mod_timer to add a new timer. However, at the same time

exit.

Still not good.
I don't know what happened, but the change of

Similar to commmit<389305b2>, it turns out that fs_info::reloc_ctl can be NULL ,
so there should be a check for rc to prevent null pointer dereference.

Actually Bartosz is handling the GPIO patches for v5.12.
I tried to merge the patch series before but failed for
various reasons.
