* This is a workaround command to perform an I2C Scan which is not as

*
* This will print "I3" if an address is already assigned for an I3C
* device and it will print "I2" if an address is already assigned for
* an I2C device. It will print RS, if the address is reserved according
* to section 5.1.2.2.5 I3C Target Address Restrictions in I3C v1.1.1.
*
* This sends I2C messages without any data (i.e. stop condition after

* is assumed there is a device present.
*
* WARNING: As there is no standard I2C detection command, this code
* uses arbitrary SMBus commands (namely SMBus quick write and SMBus
* receive byte) to probe for devices. This operation can confuse
