iio: health: afe4404: Fix oob read in afe4404_[read|write]_raw
KASAN report out-of-bounds read as follows:
BUG: KASAN: global-out-of-bounds in afe4404_read_raw+0x2ce/0x380
Read of size 4 at addr ffffffffc00e4658 by task cat/278
Call Trace:
afe4404_read_raw
iio_read_channel_info
dev_attr_show
The buggy address belongs to the variable:
afe4404_channel_leds+0x18/0xffffffffffffe9c0
This issue can be reproduce by singe command:
$ cat /sys/bus/i2c/devices/0-0058/iio\:device0/in_intensity6_raw
The array size of afe4404_channel_leds and afe4404_channel_offdacs
are less than channels, so access with chan->address cause OOB read
in afe4404_[read|write]_raw. Fix it by moving access before use them.
