scsi cdroms are scd? not sd?, also zfcp attached storage shows up as
regular scsi devices (sd? scd?), so no need to check for those (my bad).

This not how asprintf works.

You should check asprintf return != -1, when properly using asprintf
(so passing in the address of devnam as first arg) devname will not get
touched on error, so its not guaranteed to be NULL (unless you init it
as such).
