Maud Spierings 610615c966 iio: common: st_sensors: Fix use of uninitialize device structs 
commit 9f92e93e25 upstream.

Throughout the various probe functions &indio_dev->dev is used before it
is initialized. This caused a kernel panic in st_sensors_power_enable()
when the call to devm_regulator_bulk_get_enable() fails and then calls
dev_err_probe() with the uninitialized device.

This seems to only cause a panic with dev_err_probe(), dev_err(),
dev_warn() and dev_info() don't seem to cause a panic, but are fixed
as well.

The issue is reported and traced here: [1]
