The preferred git commit id reference has the form
commit <SHA-1> ("Title line")
where SHA-1 is the commit hex hash with a minimum lenth of 12 and ("Title
line") is the complete title line of the commit with a (" prefix and ")
suffix.
The current tests fail when the "Title line" has one or more embedded
double quotes.
Improve the test that finds the commit SHA-1 hex hash then ("Title line")
by using $balanced_parens for a maximum of 3 consecutive lines.

In commit e28bf1f03b ("RDMA: Convert various random sprintf sysfs _show
uses to sysfs_emit") I mistakenly used len = sysfs_emit_at to overwrite
the last trailing space of potentially multiple entry output.
Instead use a more common style by removing the trailing space from the
output formats and adding a prefixing space to the contination formats and
converting the final terminating output newline from the defective
len = sysfs_emit_at(buf, len, "\n");
to the now appropriate and typical
len += sysfs_emit_at(buf, len, "\n");

There are about 100,000 uses of 'static const <type>' but about 400 uses
of 'static <type> const' in the kernel where type is not a pointer.
The kernel almost always uses "static const" over "const static" as there
is a compiler warning for that declaration style.
But there is no compiler warning for "static <type> const".
So add a checkpatch warning for the atypical declaration uses of.

Convert all uses of:

bar = baz();
Add an imperfect test to detect these comma uses.
