Subject: [PATCH] clk: mediatek: mt8135: Fix an error handling path in clk_mt8135_apmixed_probe()

If an error occurs after mtk_alloc_clk_data(), mtk_free_clk_data() should
be called, as already done in the remove function.

Fixes: 54b7026f011e ("clk: mediatek: mt8135-apmixedsys: Convert to platform_driver and module")
