[PATCH 3/3] firewire: cdev: use kzalloc_flex() to allocate structure with byte array

[Takashi Sakamoto]

Some event structures have a trailing flexible array member of bytes to
store event-specific data. Use kzalloc_flex() to allocate the structure
together with storage for the flexible array member.
