====================
pull-request: can 2022-03-31
The first patch is by Oliver Hartkopp and fixes MSG_PEEK feature in
the CAN ISOTP protocol (broken in net-next for v5.18 only).
Tom Rix's patch for the mcp251xfd driver fixes the propagation of an
error value in case of an error.
A patch by me for the m_can driver fixes a use-after-free in the xmit
handler for m_can IP cores v3.0.x.
Hangyu Hua contributes 3 patches fixing the same double free in the
error path of the xmit handler in the ems_usb, usb_8dev and mcba_usb
USB CAN driver.
Pavel Skripkin contributes a patch for the mcba_usb driver to properly
check the endpoint type.
The last patch is by me and fixes a mem leak in the gs_usb, which was
introduced in net-next for v5.18.
