Building riscv syscall table with W=1 throws the warning as
following pattern:
arch/riscv/kernel/syscall_table.c:14:36: warning: initialized field overwritten [-Woverride-init]
14 | #define __SYSCALL(nr, call) [nr] = (call),
| ^
./include/uapi/asm-generic/unistd.h:29:37: note: in expansion of macro ‘__SYSCALL’
29 | #define __SC_COMP(_nr, _sys, _comp) __SYSCALL(_nr, _sys)
| ^~~~~~~~~
./include/uapi/asm-generic/unistd.h:34:1: note: in expansion of macro ‘__SC_COMP’
34 | __SC_COMP(__NR_io_setup, sys_io_setup, compat_sys_io_setup)
| ^~~~~~~~~
arch/riscv/kernel/syscall_table.c:14:36: note: (near initialization for ‘sys_call_table[0]’)
14 | #define __SYSCALL(nr, call) [nr] = (call),
| ^
./include/uapi/asm-generic/unistd.h:29:37: note: in expansion of macro ‘__SYSCALL’
29 | #define __SC_COMP(_nr, _sys, _comp) __SYSCALL(_nr, _sys)

arch/riscv/kernel/syscall_table.c:14:36: warning: initialized field overwritten [-Woverride-init]
...
Since we intentionally build the syscall tables this way,ignore the warning.
