Yes. I did this check before upstream this patch.
I ignored ' WARNING:MACRO_WITH_FLOW_CONTROL: Macros with flow control statements should be avoided ' warnings.
However, I didn't see any LONG_LINE warnings in the CI report here. http://mails.dpdk.org/archives/test-report/2019-July/090889.html
BTW, I think these 3 warnings in the report might be ineluctable.

The default tab size is 8. You might need to change it to 4 in the /usr/src/linux/scripts/checkpatch tool. FYI.
