csanchezdll opened a new pull request, #16224:
URL: https://github.com/apache/nuttx/pull/16224

   ## Summary
   
   This problem was introduced in https://github.com/apache/nuttx/pull/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.
