int CheckCallback();

disassembled listing :

CheckCallback:
    lui     v0,_hi(data_5A)
    lhu     v0,_lo(data_5A)(v0)
    jr      ra
    nop

source code :

static struct
{
    u_short     started;
    u_short     trapped;
    void        (*cbIntr[11])();
    u_short     mask, oldmask;
    u_long      dma;
    jmp_buf     trap;
    u_char      stack[0x1000];
} intrData;

int CheckCallback()
{
    return intrData.trapped;
}

reversed listing :

CheckCallback:
    lhu     $2,intrData+2
    j       $31
    nop
