Casting a pointer to a pointer of the same type is pointless, so remove these unnecessary casts. Around these changes: o Remove unnecessary parentheses o Use consistent dereference style (change ptr[0] to *ptr) o Argument alignment Done via coccinelle script: (and some typing) $ cat typecast_2.cocci @@ type T; T *foo; @@ - (T *)foo + foo Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: John W.
