Subject: [PATCH] net: fix SONIC_READ definition

drivers/net/jazzsonic.c:56:
#define SONIC_READ(reg) (*((volatile unsigned int *)dev->base_addr+reg))

drivers/net/sonic.h:53:
#define SONIC_CAP0             0x24

so drivers/net/jazzsonic.c:143:
val = SONIC_READ(SONIC_CAP0-i);

becomes

val = (*((volatile unsigned int *)dev->base_addr+0x24-i));

That is wrong, isn't it?
