* Bugfix free_irq()
*
* Revision 1.56 2001/08/09 11:19:39 achim
- * Scsi_Host_Template changes
+ * struct scsi_host_template changes
*
* Revision 1.55 2001/08/09 10:11:28 achim
* Command HOST_UNFREEZE_IO before cache service init.
* hdr_channel:x x - number of virtual bus for host drives
* shared_access:Y disable driver reserve/release protocol to
* access a shared resource from several nodes,
- * appropiate controller firmware required
+ * appropriate controller firmware required
* shared_access:N enable driver reserve/release protocol
* probe_eisa_isa:Y scan for EISA/ISA controllers
* probe_eisa_isa:N do not scan for EISA/ISA controllers
