====================
pull-request: can 2024-02-14
this is a pull request of 3 patches for net/master.
the first patch is by Ziqi Zhao and targets the CAN J1939 protocol, it
fixes a potential deadlock by replacing the spinlock by an rwlock.
Oleksij Rempel's patch adds a missing spin_lock_bh() to prevent a
potential Use-After-Free in the CAN J1939's
setsockopt(SO_J1939_FILTER).
Maxime Jayat contributes a patch to fix the transceiver delay
compensation (TDCO) calculation, which is needed for higher CAN-FD bit
rates (usually 2Mbit/s).
