commit a04e54f2 upstream. The following fixes a divide by zero OOPs with TYPE_TAPE due to pscsi_tape_read_blocksize() failing causing a zero sd->sector_size being propigated up via dev_attrib.hw_block_size. It also fixes another long-standing bug where TYPE_TAPE and TYPE_MEDIMUM_CHANGER where using pscsi_create_type_other(), which does not call scsi_device_get() to take the device reference. Instead, rename pscsi_create_type_rom() to pscsi_create_type_nondisk() and use it for all cases. Finally, also drop a dump_stack() in pscsi_get_blocks() for non TYPE_DISK, which in modern target-core can get invoked via target_sense_desc_format() during CHECK_CONDITION. Reported-by:
