From be460cedb67ab803c1bebceac19b1d44acb85d30 Mon Sep 17 00:00:00 2001 From: Stepan Ionichev Date: Wed, 20 May 2026 16:05:04 +0500 Subject: [PATCH] gpio: pca953x: propagate regulator_enable() error from resume pca953x_resume() returns 0 when regulator_enable() fails, dropping the real error code and masking the failure as a successful resume. The caller then proceeds as if the chip is powered, while the regulator is in fact disabled. Return ret so PM core sees the actual failure.
