Subject: [PATCH] drm/amd/pm: Fix a memory leak in an error handling path in 'vangogh_tables_init()'
Date: Thu,  5 Aug 2021 20:37:14 +0200	[thread overview]
Message-ID: <fd28a9cec24a8d32ebb26dd857c399d0a15acdd5.1628188477.git.christophe.jaillet@wanadoo.fr> (raw)

'watermarks_table' must be freed instead 'clocks_table', because
'clocks_table' is known to be NULL at this point and 'watermarks_table' is
never freed if the last kzalloc fails.

Fixes: c98ee89736b8 ("drm/amd/pm: add the fine grain tuning function for vangogh")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
