workqueue: avoid clang warning
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); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/workqueue.h:187:26: note: expanded from macro 'DECLARE_DELAYED_WORK' struct delayed_work n = __DELAYED_WORK_INITIALIZER(n, f, 0) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/workqueue.h:177:10: note: expanded from macro '__DELAYED_WORK_INITIALIZER' .work = __WORK_INITIALIZER((n).work, (f)), \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/workqueue.h:170:10: note: expanded from macro '__WORK_INITIALIZER' .data = WORK_DATA_STATIC_INIT(), \ ^~~~~~~~~~~~~~~~~~~~~~~ include/linux/workqueue.h:111:39: note: expanded from macro 'WORK_DATA_STATIC_INIT' ATOMIC_LONG_INIT(WORK_STRUCT_NO_POOL | WORK_STRUCT_STATIC) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~ include/asm-generic/atomic-long.h:32:41: note: expanded from macro 'ATOMIC_LONG_INIT' #define ATOMIC_LONG_INIT(i) ATOMIC_INIT(i) ~~~~~~~~~~~~^~ 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.
