[Qemu-devel] [PATCH v2 13/30] trace: Fix parameter types in hw/char

[Eric Blake <eblake@redhat.com>]

An upcoming patch will let the compiler warn us when we are silently
losing precision in traces.  In most cases, we just update the
trace definitions to match the caller types; but in one case, the
caller had already done 'val &= 0xff' so casting uint64_t val down
to the type expected by the trace is sufficient.
