Subject: checkpatch: improve EMBEDDED_FUNCTION_NAME test
The existing behavior relies on patch context to identify function
declarations. Add the ability to find function declarations when there is
an open brace in column 1.
This finds function declarations only in specific single line forms where
the function name is on a single line like:
int foo(args...)
{
and
int
foo(args...)
{
It does not recognize function declarations like:
int foo(int bar,
int baz)
{
