The patch titled
Subject: checkpatch: improve macros with flow control test

checkpatch-improve-macros-with-flow-control-test.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: checkpatch: improve macros with flow control test
The current test excludes any macro with ## concatenation from being
reported with hidden flow control.
Some macros are used with return or goto statements along with ##args or
##__VA_ARGS__. A somewhat common case is a logging macro like
pr_info(fmt, ...) then a return or goto statement.
Check the concatenated variable for args or __VA_ARGS__ and allow those
macros to also be reported when they contain a return or goto.
