Read of size 4 at addr ffffffffc02ac638 by task cat/279

Call Trace:
afe4403_read_raw
iio_read_channel_info
dev_attr_show

The buggy address belongs to the variable:
afe4403_channel_leds+0x18/0xffffffffffffe9e0

This issue can be reproduced by singe command:

$ cat /sys/bus/spi/devices/spi0.0/iio\:device0/in_intensity6_raw

The array size of afe4403_channel_leds is less than channels, so access
