Subject: checkpatch: Add --strict test for function pointer calling style
Peter Hurley wrote:
The use of older function ptr calling style, (*fn)(), makes static
analysis more error-prone; replace with modern fn() style.
So make checkpatch emit a --strict test for that condition.
Update the unnecessary parentheses test for dereferencing
objects at the same time and create a $fix mechanism too.
