Hello Jakub, hello David,

this is a pull request of 2 patches for net/master.

Baruch Siach's patch fixes a typo for the Microchip CAN BUS Analyzer
Tool entry in the MAINTAINERS file.

Hussein Alasadi fixes the setting of the M_CAN_DBTP register in the
m_can driver. The regression git mainline in v5.14-rc1, so no backport
to stable is needed.

regards,
Marc

[PATCH net 2/2] can: m_can: m_can_set_bittiming(): fix setting M_CAN_DBTP register

[Marc Kleine-Budde]

From: Hussein Alasadi <alasadi@arecs.eu>

This patch fixes the setting of the M_CAN_DBTP register contents:
- use DBTP_ (the data bitrate macros) instead of NBTP_ which area used
  for the nominal bitrate
- do not overwrite possibly-existing DBTP_TDC flag by ORing reg_btp
  instead of overwriting

Fixes: 20779943a080 ("can: m_can: use bits.h macros for all regmasks")
