Merge patch series "Constify most SCSI host templates"

Bart Van Assche <bvanassche@acm.org> says:

It helps humans and the compiler if it is made explicit that SCSI host
templates are not modified. Hence this patch series that constifies most
SCSI host templates. Please consider this patch series for the next merge
window.
