Re: [PATCH net-next 01/11] atm: horizon: shut up clang null pointer arithmetic warning

Also in:
lkml
- for (mem = (HDW *) memmap; mem < (HDW *) (memmap + 1); ++mem) + for (mem = (HDW *) memmap; mem < (HDW *) ((uintptr_t)memmap + 1); ++mem)
Note that these two lines are semantically different. In the first line, "+ 1" moves the pointer by (sizeof memmap) bytes. However in the second line, "+ 1" moves the pointer by only 1 byte. This driver is old, but let's still keep its code correct!
