From 4e5b0b7c5d95814b6d76911a91572a0691925ca7 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Mon, 10 Aug 2026 10:53:35 +0300 Subject: [PATCH] iio: light: rohm-bu27034: Fix error return When BU27034 fails to read gain value at integration-time setting, it returns 0. This leaves caller unaware of the fact that setting the integration time failed. Fix this by returning the relevant error instead of zero.
