/**
* @brief Send all the queued commands on the I2C bus, in master mode.
* The task will be blocked until all the commands have been sent out.
- * The I2C APIs are not thread-safe, if you want to use one I2C port in different tasks,
- * you need to take care of the multi-thread issue.
+ * The I2C port is protected by mutex, so this function is thread-safe.
* This function shall only be called in I2C master mode.
*
* @param i2c_num I2C port number
