From e7c31aac98c16e3562a6efc96c60f053d94898d3 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 31 Aug 2025 12:48:21 +0200 Subject: [PATCH] iio: consumers: Fix offset handling in iio_convert_raw_to_processed() [ Upstream commit 33f5c69c4daff39c010b3ea6da8ebab285f4277b ] Fix iio_convert_raw_to_processed() offset handling for channels without a scale attribute. The offset has been applied to the raw64 value not to the original raw value. Use the raw64 value so that the offset is taken into account.
