Subject: cmd/io.c: Fix comparison of unsigned expression warning
X-Git-Tag: v2017.07-rc1~290

cmd/io.c: Fix comparison of unsigned expression warning

The function cmd_get_data_size() returns an int and not unsigned.  So we
should assign it to an int rather than unsigned so that we can later
compare the return value.  Reported by clang-3.8.
