[PATCH 03/27] iio: chemical: scd30: Switch to sparse friendly claim/release_direct()

[Jonathan Cameron <jic23@kernel.org>]

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

This driver caused a false positive with __cond_lock() style solution
but is fine with the simple boolean return approach now used.

Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

v1: Adapted due to new use of guards() in previous patch.
