Subject: [PATCH net 0/n] pull-request: can 2024-08-30

Hello netdev-team,

this is a pull request of 13 patches for net/master.

The first patch is by Kuniyuki Iwashima for the CAN BCM protocol that
adds a missing proc entry removal when a device unregistered.

Simon Horman fixes the cleanup in the error cleanup path of the m_can
driver's open function.

Markus Schneider-Pargmann contributes 7 fixes for the m_can driver,
all related to the recently added IRQ coalescing support.

The next 2 patches are by me, target the mcp251xfd driver and fix ring
and coalescing configuration problems when switching from CAN-CC to
CAN-FD mode.

Simon Arlott's patch fixes a possible deadlock in the mcp251x driver.

The last patch is by Martin Jocic for the kvaser_pciefd driver and
fixes a problem with lost IRQs, which result in starvation, under high
load situations.

regards,
Marc
