Thus, casting (unsigned long *)(unsigned long) is necessary to fix the following sparse warnings. drivers/tty/serial/samsung.c:142:33: warning: cast removes address space of expression drivers/tty/serial/samsung.c:161:33: warning: cast removes address space of expression drivers/tty/serial/samsung.c:176:33: warning: cast removes address space of expression drivers/tty/serial/samsung.c:526:40: warning: cast removes address space of expression Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/tty/serial/samsung.h b/drivers/tty/serial/samsung.h index 00a499ecd385..aaa617a6c499 100644 --- a/drivers/tty/serial/samsung.h +++ b/drivers/tty/serial/samsung.h @@ -68,7 +68,8 @@ struct s3c24xx_uart_port { /* register access controls */ #define portaddr(port, reg) ((port)->membase + (reg)) -#define portaddrl(port, reg) ((unsigned long *)((port)->membase + (reg))) +#define portaddrl(port, reg) \ + ((unsigned long *)(unsigned long)((port)->membase + (reg))) #define rd_regb(port, reg) (__raw_readb(portaddr(port, reg))) #define rd_regl(port, reg) (__raw_readl(portaddr(port, reg)))
