ath9k驱动不能正常记载导致板子一直重启

qca9563 ath9k
内核 4.9.131
openwrt ap152

static int ath_ahb_probe(struct platform_device *pdev)
{
ret = ath9k_init_device(dev_id, sc, &ath_ahb_bus_ops);
}
int ath9k_init_device(u16 devid, struct ath_softc *sc,
const struct ath_bus_ops *bus_ops)
{

error = ath9k_init_softc(devid, sc, bus_ops);
}

static int ath9k_init_softc(u16 devid, struct ath_softc *sc,
const struct ath_bus_ops *bus_ops)
{
ret = ath9k_hw_init(ah);
}
int ath9k_hw_init(struct ath_hw *ah)
{
int ret;
struct ath_common *common = ath9k_hw_common(ah);
}

static inline struct ath_common *ath9k_hw_common(struct ath_hw *ah)
{
return &ah->common;
}

ath9k驱动调用该函数导致cup挂掉，具体如图，求助大神指导，或者给点思路。

这个问题不是MCP23017的问题，这个是无线驱动的问题，更上一个问题没有关系。谢谢你的回答。
