Summary
This problem was introduced in #16199
In that PR, the assignment of "ret" variable was removed so now this variable might be used in uninitialized status when ioctl(...SIOCSCANBITRATE...) is called.
Impact
ioctl calls for CAN interfaces on stm32h7 can return as failed when they effectively succeeded.
Testing
The error was found due to a compiler warning after the previous PR was already merged.
