Subject: firewire: core: make address handler length 64 bits
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=188726ecb66f022e92ec110ca85c62a937184636;p=deliverable%2Flinux.git

firewire: core: make address handler length 64 bits

The type of the length field of the fw_address_handler structure was
size_t, which restricted it to 32 bits on 32-bit architectures.

While making it u32 would match the userspace API, all calculations on
this field use 64 bits anyway, and the ability to use 4 GB or larger
address ranges is useful in the kernel.
