Revert "iio:humidity:si7020: fix pointer to i2c client"
commit e765537a upstream. This reverts commit e0922e5e. Requested by Andrey Smirnov. It incorrectly assumes that the level of indirection is not needed which is not true(probably because the driver incorrectly allocates sizeof(*client) instead of sizeof(*data) via devm_iio_device_alloc). If you look at the code of the probe function(see below) it is easy to see that what is being stored in the private memory of the IIO device instance is not a copy of a 'struct i2c_client' but a pointer to an instance passed as an argument to the probe function. struct i2c_client **data; int ret; < Some code skipped > indio_dev = devm_iio_device_alloc(&client->dev, sizeof(*client)); if (!indio_dev) return -ENOMEM; data = iio_priv(indio_dev); *data = client; Without reverting this change any read of a raw value of this sensor leads to a kernel oops due to a NULL pointer de-reference on my hardware setup.
