From acbf58e530416e167c3b323111f4013d9f2b0a7d Mon Sep 17 00:00:00 2001 From: Lucas Tanure Date: Wed, 28 Jul 2021 11:44:16 +0100 Subject: [PATCH] ASoC: wm_adsp: Let soc_cleanup_component_debugfs remove debugfs soc_cleanup_component_debugfs will debugfs_remove_recursive the component->debugfs_root, so adsp doesn't need to also remove the same entry. By doing that adsp also creates a race with core component, which causes a NULL pointer dereference Signed-off-by: Lucas Tanure Link: https://lore.kernel.org/r/20210728104416.636591-1-tanureal@opensource.cirrus.com Signed-off-by: Mark Brown --- sound/soc/codecs/wm_adsp.c | 1 - 1 file changed, 1 deletion(-) diff --git a/sound/soc/codecs/wm_adsp.c b/sound/soc/codecs/wm_adsp.c index 549d98241dae..fe15cbc7bcaf 100644 --- a/sound/soc/codecs/wm_adsp.c +++ b/sound/soc/codecs/wm_adsp.c @@ -747,7 +747,6 @@ static void wm_adsp2_init_debugfs(struct wm_adsp *dsp, static void wm_adsp2_cleanup_debugfs(struct wm_adsp *dsp) { wm_adsp_debugfs_clear(dsp); - debugfs_remove_recursive(dsp->debugfs_root); } #else static inline void wm_adsp2_init_debugfs(struct wm_adsp *dsp, -- 2.11.0
