The parse config function now performs action on the device either
reading or writing and a reset.  If the regulator is managed it needs
to be turned on.  So turn on the regulator if available if the parsing
fails then turn off the regulator.
Another BTW:
Consider converting the switching of the vsup to runtime_pm.

Yet another one:
Why do you disable the clocks in the error path of tcan4x5x_can_probe(),
but never enable them?
out_clk:
	if (!IS_ERR(mcan_class->cclk)) {
		clk_disable_unprepare(mcan_class->cclk);
		clk_disable_unprepare(mcan_class->hclk);
	}
- please move the clock handling from the m_can.c to the individual
  driver
- please move the clock handling to runtime_pm in the individual driver
- remove the obsolete m_can_class_get_clocks()
- make runtime_pm mandatory

regards,
Marc
