Subject: pull-request: can 2020-11-15

Hello Jakub, hello David,

here's a pull request for net/master consisting of 15 patches for net/master,
with the fixes tags corrected.

Anant Thazhemadam contributed two patches for the AF_CAN that prevent potential
access of uninitialized member in can_rcv() and canfd_rcv().

The next patch is by Alejandro Concepcion Rodriguez and changes can_restart()
to use the correct function to push a skb into the networking stack from
process context.

Zhang Qilong's patch fixes a memory leak in the error path of the ti_hecc's
probe function.

A patch by me fixes mcba_usb_start_xmit() function in the mcba_usb driver, to
first fill the skb and then pass it to can_put_echo_skb().

Colin Ian King's patch fixes a potential integer overflow on shift in the
peak_usb driver.

The next two patches target the flexcan driver, a patch by me adds the missing
"req_bit" to the stop mode property comment (which was broken during net-next
for v5.10). Zhang Qilong's patch fixes the failure handling of

The next seven patches target the m_can driver including the tcan4x5x spi
driver glue code. Enric Balletbo i Serra's patch for the tcan4x5x Kconfig fix
the REGMAP_SPI dependency handling. A patch by me for the tcan4x5x driver's
probe() function adds missing error handling to for devm_regmap_init(), and in
tcan4x5x_can_remove() the order of deregistration is fixed. Wu Bo's patch for
the m_can driver fixes the state change handling in
m_can_handle_state_change(). Two patches by Dan Murphy first introduce
m_can_class_free_dev() and then make use of it to fix the freeing of the can
device. A patch by Faiz Abbas add a missing shutdown of the CAN controller in
the m_can_stop() function.
