From ee7a0a9daa8e918ef60cbd5c563794ad8b675ba8 Mon Sep 17 00:00:00 2001 From: Zicheng Qu Date: Sat, 2 Nov 2024 09:25:25 +0000 Subject: [PATCH] iio: Fix fwnode_handle in __fwnode_iio_channel_get_by_name() commit 3993ca4add248f0f853f54f9273a7de850639f33 upstream. In the fwnode_iio_channel_get_by_name(), iterating over parent nodes to acquire IIO channels via fwnode_for_each_parent_node(). The variable chan was mistakenly attempted on the original node instead of the current parent node. This patch corrects the logic to ensure that __fwnode_iio_channel_get_by_name() is called with the correct parent node.
