Subject: [PATCH] spi: microchip-core: Fix the error handling path in mchp_corespi_probe()
Date: Sat, 11 Jun 2022 09:37:46 +0200	[thread overview]
Message-ID: <a90bec10dec43719b12afdb967e87526c4bc849a.1654933052.git.christophe.jaillet@wanadoo.fr> (raw)

clk_prepare_enable() is called instead of clk_disable_unprepare() in the
error handling path of the probe function.

Change the function that is called so that resources are released
correctly.

Fixes: 9ac8d17694b6 ("spi: add support for microchip fpga spi controllers")
