From b3e1cf31154136da855f3cb6117c17eb0b6bcfb4 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET christophe.jaillet@wanadoo.fr Date: Sun, 7 Aug 2022 08:56:38 +0200 Subject: [PATCH] mmc: meson-gx: Fix an error handling path in meson_mmc_probe()
The commit in Fixes has introduced a new error handling which should goto the existing error handling path. Otherwise some resources leak.
