net: Remove casts to same type
Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force and __user. @@ type T; T *p; @@ - (T *)p + p Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
