From 798fa301e19ffc8fc23e5d8c9ea2078e5bc9796a Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 9 Feb 2025 18:06:19 +0000 Subject: [PATCH] iio: dac: ad3552r-hs: Stop using iio_device_claim_direct_scoped() This complex cleanup.h use case of conditional guards has proved to be more trouble that it is worth in terms of false positive compiler warnings and hard to read code. Move directly to the new claim/release_direct() that allow sparse to check for unbalanced context.
