Subject: iio: proximity: hx9023s: Switch to sparse friendly iio_device_claim/release_direct()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9dc7ed3bfe437b3a9fc5399fbe594a4b054eeeec;p=users%2Fjedix%2Flinux-maple.git

iio: proximity: hx9023s: Switch to sparse friendly iio_device_claim/release_direct()

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.
