Generally it's best to avoid unnecessary casts. As a human reader, I find the cast confusing. It indicates that DPAA2_ETH_MFL somehow requires special handling. Perhaps it's negative or we are trying to truncate away the high bits. But neither of those things really make sense. >From a static analysis perspective if DPAA2_ETH_MFL doesn't fit nicely then we would want to generate a warning. But the cast explicitly disables the check. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
