[Qemu-devel] [PATCH V2 1/2] migration/qemu-file: remove check on writev_buffer in qemu_put_compression_data

[Wei Yang]

From: Wei Yang <address@hidden>

The check of writev_buffer is in qemu_fflush, which means it is not
harmful if it is NULL.

And removing it will make the code consistent since all other
add_to_iovec() is called without the check.
