Hello!

I think in HAL CAN driver have error in function

HAL_CAN_Transmit_IT

I put part of driver here 

https://pastebin.com/PhHcMC94

on line 13 we see

1.     __HAL_LOCK

   (

   hcan

   )

   ;

next on line 29 we see

1. if

   (

   transmitmailbox

   !=

   CAN_TXSTATUS_NOMAILBOX

   )

and next execute only if statement true

1.       __HAL_UNLOCK

   (

   hcan

   )

   ;

If system haven't free mailbox hcan instense not unlocked. And i cant execute any funtion because his instanse locked.

I'm not sure that I'm right. If I'm not right, explain why it's written like that.

#lock #can-hal_can_transmit_it #can
