Subject[PATCH AUTOSEL 5.12 52/80] spi: meson-spicc: fix a wrong goto jump for avoiding memory leak.
Date
From: zpershuai <zpershuai@gmail.com>

[ Upstream commit 95730d5eb73170a6d225a9998c478be273598634 ]

In meson_spifc_probe function, when enable the device pclk clock is
error, it should use clk_disable_unprepare to release the core clock.
