Meet 'detected buffer overflow in memcpy' with pxe1610 driver probe

[Andy Zhang]

Dear guys,

I meet an issue when I use comand 'echo pxe1610 0x6e > /sys/bus/i2c/devices/i2c-0/new_device' to export pxe1610 driver.
The kernel version I used is: dev-5.4 (linux-aspeed-5.4.43)
And the detail error logs are as below:
