From dca02651cee78260ad9b6f1dce8f40b28367b7e2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 10 May 2017 08:51:09 +0300 Subject: [PATCH] iio: adc: ti_am335x_adc: allocating too much in probe 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.
