Building with clang shows lots of warning like:
drivers/amba/bus.c:447:8: warning: implicit conversion from 'long long' to
'int' changes value from 4294967248 to -48
[-Wconstant-conversion]
static DECLARE_DELAYED_WORK(deferred_retry_work, amba_deferred_retry_func);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

struct delayed_work n = __DELAYED_WORK_INITIALIZER(n, f, 0)

.work = __WORK_INITIALIZER((n).work, (f)), \

arch/arm/include/asm/atomic.h:21:27: note: expanded from macro 'ATOMIC_INIT'
#define ATOMIC_INIT(i) { (i) }
~ ^
This makes the type cast explicit, which shuts up the warning.
