Subject: iio: adc: ti_am335x_adc: allocating too much in probe
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 5ba5b437efaa7a502eec393c045d3bf90c92c4e9 upstream.
We should be allocating enough information for a tiadc_device struct
which is about 400 bytes but instead we allocate enough for a second
iio_dev struct which is over 2000 bytes.
