From 18abe5f4c3c6c3436c82382502c437505a7bd1ba Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Fri, 9 Jun 2023 11:28:03 +0200 Subject: [PATCH] mfd: stmfx: Fix error path in stmfx_chip_init [ Upstream commit f592cf624531286f8b52e40dcfc157a5a7fb115c ] In error path, disable vdd regulator if it exists, but don't overload ret. Because if regulator_disable() is successful, stmfx_chip_init will exit successfully while chip init failed.
