Subject: [PATCH] memory: mvebu-devbus: Fix missing clk_disable_unprepare in mvebu_devbus_probe()
Date:   Sat, 26 Nov 2022 12:49:11 +0800

Precedence: bulk

The clk_disable_unprepare() should be called in the error handling
of devbus_get_timing_params() and of_platform_populate(), fix it by
replacing devm_clk_get and clk_prepare_enable by devm_clk_get_enabled.

Fixes: e81b6abebc87 ("memory: add a driver for atmel ram controllers")
