x86/io_delay: Break instead of fallthrough in switch statement The current code is fine since 'case CONFIG_IO_DELAY_TYPE_NONE' does nothing, but scripts/checkpatch.pl complains about this: warning: Possible switch case/default not preceded by break or fallthrough comment I like break statement better than a fallthrough comment here. It avoids the warning and clarify the code. No behavior change is intended.
