[merged] checkpatch-add-fix-option-for-some-trailing_statements.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: checkpatch: add --fix option for some TRAILING_STATEMENTS
has been removed from the -mm tree.  Its filename was
     checkpatch-add-fix-option-for-some-trailing_statements.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Joe Perches <joe@perches.com>
Subject: checkpatch: add --fix option for some TRAILING_STATEMENTS

Single line code like:

	if (foo) bar;

should generally be written:

	if (foo)
		bar;

Add a --fix test to do so.

This fix is not done when an ASSIGN_IN_IF in the same line exists.
