To distinguish between resets sent by the SCSI mid-level error handling and newly introduced devices (LUs), this Unit Attention: power on, reset, or bus reset occurred [0x29,0x0] has been subdivided into that UA for the reset case and this new UA: power on occurred [0x29,0x1] for the new device (LU) case. This makes debug a little easier to follow when it is turned on (e.g. 'echo 0x1 > opts'). Bump driver version number.
