Subject: [PATCH 5.13 061/151] drm/amd/pm: Fix a memory leak in an error handling path in vangogh_tables_init()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 5126da7d99cf6396c929f3b577ba3aed1e74acd7 ]

'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")
