The range of "enum" types varies from one ABI to another. If the enums being tested in these functions happen to be 16 bits wide, then GCC may issue a warning because, in such a case, the comparison is always true. Using an int instead of a uint16_t avoids that particular problem and should suppress the warning. Fixes the following reported warnings: lib/ofp-print.c:240: warning: comparison is always true due to limited range of data type lib/ofp-util.c:1973: warning: comparison is always false due to limited range of data type Reported-by: YAMAMOTO Takashi <yamamoto@valinux.co.jp>
