Subject[PATCH v11 06/13] ima: Use designated initializers for struct ima_event_data
Date
Designated initializers allow specifying only the members of the struct
that need initialization. Non-mentioned members are initialized to zero.

This makes the code a bit clearer (particularly in ima_add_boot_aggregate)
and also allows adding a new member to the struct without having to update
all struct initializations.
