[PATCH 5.9 024/105] can: m_can: tcan4x5x_can_probe(): fix error path: remove erroneous clk_disable_unprepare()

[Greg Kroah-Hartman]

From: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>

[ Upstream commit ad1f5e826d91d6c27ecd36a607ad7c7f4d0b0733 ]

The clocks mcan_class->cclk and mcan_class->hclk are not prepared by any call
during tcan4x5x_can_probe(), so remove erroneous clk_disable_unprepare() on
them.

Fixes: 5443c226ba91 ("can: tcan4x5x: Add tcan4x5x driver to the kernel")
