Some callers of scsi_execute_cmd() (like e.g. sd_spinup_disk()) are

Shouldn't the scsi_execute_cmd() callers be fixed instead of modifying scsi_execute_cmd(), e.g. by zero-initializing the sshdr structure?

This would be possible, yes, but introducing new buggy callers could happen.

Additionally the amount of code churn would be much larger.
