[RFC 13/17] ipc: use __ARCH_WANT_IPC_PARSE_VERSION in ipc/util.h

[arnd@arndb.de]

[-- Attachment #1: 0022-ipc-use-__ARCH_WANT_IPC_PARSE_VERSION-in-ipc-util.h.patch --]
[-- Type: text/plain, Size: 958 bytes --]

The definition of ipc_parse_version depends on
__ARCH_WANT_IPC_PARSE_VERSION, but the header file
declares it conditionally based on the architecture.

Use the macro consistently to make it easier to add
new architectures.
