scsi_dev_info_list_add_keyed - add one dev_info list entry. : if true, null terminate short strings. Otherwise space pad. : vendor string : model (product) string : integer string : if strflags NULL, use this flag value : specify list to use

Description: Create and add one dev_info entry for , , or in list specified by . If , add to the tail of the list, do not space pad, and set devinfo->compatible. The scsi_static_device_list entries are added with 1 and NULL.

Returns: 0 OK, -error on failure.

int scsi_dev_info_remove_list ( int key )

scsi_dev_info_remove_list - destroy an added devinfo list : key of the list to destroy

Iterates over the entire list first, freeing all the values, then frees the list itself. Returns 0 on success or -EINVAL if the key can't be found.
