Subject: iio: pressure: zpa2326: Switch to sparse friendly iio_device_claim/release_direct()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=66024cb953d2a89078374cff459c0cefaa4c576b;p=users%2Fjedix%2Flinux-maple.git

iio: pressure: zpa2326: 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.
