The io_timeout property, introduced in c9b6609 (part of 6.0) is silently overwritten by the hardcoded default value of 30 seconds (DEFAULT_IO_TIMEOUT) in scsi_generic_realize because that function is being called after the properties have already been applied. The property definition already has a default value which is applied correctly when no value is explicitly set, so we can just remove the code which overrides the io_timeout completely. This has been tested by stracing SG_IO operations with the io_timeout property set and unset and now sets the timeout field in the ioctl request to the proper value.
