[PATCH v2 6/8] iio: adc: ti-ads1015: Switch to sparse friendly iio_device_claim/release_direct()

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

These new functions allow sparse to find failures to release
direct mode reducing chances of bugs over the claim_direct_mode()
functions that are deprecated.
