From: Joe Perches <joe@xxxxxxxxxxx>
Subject: checkpatch: Add some --strict coding style checks
Argument alignment across multiple lines should match the open
parenthesis.
Logical continuations should be at the end of the previous line, not the
start of a new line.
These are not required by CodingStyle so make the tests active only when
using --strict.
Tested with:
int foo(void)
{
if (foo &&
bar())
baz();
if (foo &&
bar())
baz();
foo_some_long_function(bar,
baz);
foo_some_long_function(bar,
baz);
return 0;
}
