Subject: [PATCH 6.7 487/713] clk: mediatek: mt7622-apmixedsys: Fix an error handling path in clk_mt8135_apmixed_probe()

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

[ Upstream commit a32e88f2b20259f5fe4f8eed598bbc85dc4879ed ]

'clk_data' is allocated with mtk_devm_alloc_clk_data(). So calling
mtk_free_clk_data() explicitly in the remove function would lead to a
double-free.

Remove the redundant call.

Fixes: c50e2ea6507b ("clk: mediatek: mt7622-apmixedsys: Add .remove() callback for module build")
