From 13c27e946ddc0e19f3d8b307b14cd8053fcb4844 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 25 May 2016 09:40:26 +0200 Subject: [PATCH] iio: bh1780: dereference the client properly The code in runtime_[suspend|resume] was assuming that the i2c client data was the bh1780 state container, but it contains the IIO device. So first dereference the IIO device from the i2c client, then get the state container using the iio_priv() call.
