Subject: checkpatch: improve "no space after cast" test
Some false positives exist on this test.
For instance:
*va_arg(args, signed char *) = val.s;
or
memset(foo, 0, sizeof(struct bar *) * baz));
Ignore lines that have an arithmetic operator or assignment
after what appears to be a cast to a pointer "(foo *)".
Add $Arithmetic convenience variable.
