From 64774dea58969194ea5c27fa639954e551a87024 Mon Sep 17 00:00:00 2001 From: Ruoyu Wang Date: Sat, 20 Jun 2026 16:04:06 +0800 Subject: [PATCH] bus: qcom-ebi2: Fix clock leak on probe failure qcom_ebi2_probe() enables the EBI2X and EBI2 clocks before it walks child nodes and populates child devices. If reading a child node's reg property fails, or if of_platform_default_populate() fails, probe returns without disabling either clock. Route those failure paths through the existing clock cleanup labels so a failed probe does not leave the clocks prepared and enabled.
